-Four phases when loading a Vim9 script ~
-
-In legacy script the functions are created when encountered, but parsed only
-when used.  This allows for defining functions in any order and having them
-call each other, so long as the function is defined when it is called: >
-	func One()
-	   call Two()
-	endfunc
-	func Two()
-	   if cond
-	      call One()  " recursive call
-	   endif
-	endfunc
-	call One()
-
-In Vim9 script the functions are compiled.  When using the same functions as
-the above example it is not possible to compile function One without knowing
-that function Two exists. Or this would require a runtime check, which is slow
-and does not allow for compile time type checking.
-
-When sourcing a Vim9 script this happens in four phases:
-1. Cleanup: If the script was sourced before all script-local variables,
-   imports and functions are deleted.
-2. Discovery: The script is read and declarations of functions, imports and
-   variables are recognized and the type is parsed.  Variable initializers
-   that are a constant are evaluated, this can also give the type of the
-   variable.
-3. Compilation: Functions are compiled.  The script-local functions, imports
-   and variables from the discovery phase are found and types are checked.
-4. Execution: the commands in the script are executed, top to bottom.
-   Functions are skipped over, they do do not need to be processed again.
-   Variable initializers are evaluated when encountered.  Note that if a
-   function called earlier has set the value this will be over-written. It is
-   best to declare variables before where they are used to avoid confusion.
-
-The result is that items defined at the script level can be used anywhere in
-the script. This allows for putting the main function at the top: >
-	def Main()
-	  SubOne()
-	  SubTwo()
-	enddef
-	def SubOne()
-	  ...
-	def SubTwo()
-	  ...
-
-Note that script-local variables should either have a type defined or have a
-constant initializer.  Otherwise an error is given for the type being unknown.
