Patch 8.2.0818
Problem: Vim9: using a discovery phase doesn't work well.
Solution: Remove the discovery phase, instead compile a function only when
it is used. Add :defcompile to compile def functions earlier.

THIS IS STILL UNDER DEVELOPMENT - ANYTHING CAN BREAK - ANYTHING CAN CHANGE
! Vim script has been growing over time, while keeping backwards compatibility.
! That means bad choices from the past often can't be changed. Execution is
! quite slow, every line is parsed every time it is executed.
!
! The main goal of Vim9 script is to drastically improve performance. An
! increase in execution speed of 10 to 100 times can be expected. A secondary
! goal is to avoid Vim-specific constructs and get closer to commonly used
! programming languages, such as JavaScript, TypeScript and Java.
The performance improvements can only be achieved by not being 100% backwards
compatible. For example, in a function the arguments are not available in the
! "a:" dictionary, as creating that dictionary adds quite a lot of overhead.
! Other differences are more subtle, such as how errors are handled.
The Vim9 script syntax and semantics are used in:
- a function defined with the `:def` command
- a script file where the first command is `vim9script`
When using `:function` in a Vim9 script file the legacy syntax is used.
! However, this is discouraged.
! Vim9 script and legacy Vim script can be mixed. There is no need to rewrite
! old scripts, they keep working as before.

In Vim script comments normally start with double quote. That can also be the

Vim9 functions ~
`:def` has no extra arguments like `:function` does: "range", "abort", "dict"
or "closure". A `:def` function always aborts on an error, does not get a
range passed and cannot be a "dict" function.

Vim9 functions ~
+ A function defined with `:def` is compiled. Execution is many times faster,
+ often 10x to 100x times.
+
+ Many errors are already found when compiling, before the function is executed.
+ The syntax is strict, to enforce code that is easy to read and understand.
+
+ Compilation is done when the function is first called, or when the `:compile`
+ command is encountered in the script where the function was defined.
+
`:def` has no extra arguments like `:function` does: "range", "abort", "dict"
or "closure". A `:def` function always aborts on an error, does not get a
range passed and cannot be a "dict" function.
! The argument types and return type need to be specified. The "any" type can
! be used, type checking will then be done at runtime, like with legacy
! functions.
!
! Arguments are accessed by name, without "a:". There is no "a:" dictionary or
! "a:000" list.
!
! Variable arguments are defined as the last argument, with a name and have a
! list type, similar to Typescript. For example, a list of numbers: >
! def MyFunc(...itemlist: list<number>)
for item in itemlist
...
+ Functions and variables are script-local by default ~
+
+ When using `:function` or `:def` to specify a new function at the script level
+ in a Vim9 script, the function is local to the script, as if "s:" was
+ prefixed. Using the "s:" prefix is optional.
+
+ To define or use a global function or variable the "g:" prefix must be used.
+
+ When using `:function` or `:def` to specify a new function inside a function,
+ the function is local to the function. It is not possible to define a
+ script-local function inside a function. It is possible to define a global
+ function, using the "g:" prefix.
+
+ When referring to a function and no "s:" or "g:" prefix is used, Vim will
+ search for the function in this order:
+ - Local to the current scope and outer scopes up to the function scope.
+ - Local to the current script file.
+ - Imported functions, see `:import`.
+ In all cases the function must be defined before used. To make a call cycle a
+ global function needs to be used. (TODO: can we fix this?)
+
+ The result is that functions and variables without a namespace can always be
+ found in the script, either defined there or imported. Global functions and
+ variables could be defined anywhere (good luck finding where!).
+
+ Global functions can be still be defined and deleted at nearly any time. In
+ Vim9 script script-local functions are defined once when the script is sourced
+ and cannot be deleted.
