 Further Vim9 improvements, possibly after launch:
-- For map(), reduce() and filter() use a specific implementation if the second
-  argument is a compiled function.  #11163
 - Use Vim9 for more runtime files.
-- Check performance with callgrind and kcachegrind.
-    getline()/substitute()/setline() in #5632
-- Better implementation for partial and tests for that.
-- when using "const" mark the variable type as const with TTFLAG_CONST, so
-  that an error is given at compile time when trying to change it.  E.g. for a
-  const list and trying to call add().
-- Compile options that are an expression, e.g. "expr:" in 'spellsuggest',
-  'foldexpr', 'foldtext', 'printexpr', 'diffexpr', 'patchexpr', 'charconvert',
-  'balloonexpr', 'includeexpr', 'indentexpr', 'formatexpr'.
-  Give an error if compilation fails. (#7625)
-  Alternatively: Detect a compiled function call and skip the expression
-  evaluation.
-  Use the location where the option was set for deciding whether it's to be
-  evaluated in Vim9 script context.
 - implement :type
 - implement :enum
 - implement :class and :interface: See |vim9-classes|
-- For range: make table of first ASCII character with flag to quickly check if
-  it can be a Vim9 command. E.g. "+" can, but "." can't.
 - Inline call to map() and filter(), better type checking.
-- Make accessing varargs faster: arg[expr]
-	EVAL expr
-	LOADVARARG (varargs idx)
 - When evaluating constants for script variables, some functions could work:
     has(featureName), len(someString)
