Patch 7.4.260
Problem: It is possible to define a function with a colon in the name. It
is possible to define a function with a lower case character if a
"#" appears after the name.
Solution: Disallow using a colon other than with "s:". Ignore "#" after the
name.

A Funcref variable must start with a capital, "s:", "w:", "t:" or "b:". You
+ can use "g:" but the following name must still start with a capital. You
cannot have both a Funcref variable and a function with the same name.
A special case is defining a function and directly assigning its Funcref to a

function from a mapping defined in the script, but then |<SID>| must be used
instead of "s:" when the mapping is expanded outside of the script.
