Patch 8.2.2223
Problem: Vim9: Reloading marks a :def function as deleted.
Solution: Clear the function contents but keep the index.

def g:SomeFunc()
....
- There is one gotcha: If a compiled function is replaced and it is called from
- another compiled function that is not replaced, it will try to call the
- function from before it was replaced, which no longer exists. This doesn't
- work: >
- vimscript noclear
-
- def ReplaceMe()
- echo 'function redefined every time'
- enddef
-
- if exists('s:loaded') | finish | endif
- var s:loaded = true
-
- def NotReplaced()
- ReplaceMe() # Error if ReplaceMe() was redefined
- enddef
-

The startling truth finally became apparent, and it was this: Numbers
written on restaurant checks within the confines of restaurants do not follow
the same mathematical laws as numbers written on any other pieces of paper in
any other parts of the Universe. This single statement took the scientific
world by storm. So many mathematical conferences got held in such good
restaurants that many of the finest minds of a generation died of obesity and
heart failure, and the science of mathematics was put back by years.
