I have some suggestions of change to freepascal syntax, just to debate
(All are backward compatible)
- Declaring variables inside blocks, and loop variables
- Autofree pointers
- Try except finally blocks
- Private declarations in implementation
some of them can be found in
https://www.codeproject.com/Articles/1252167/Delphi-Language-Progression-Suggestions
Some can be considered regressions, not progression.
autofree pointers will be available with management operators, I suppose.
probably try except finally blocks is still doable.
But declaring variables inside code blocks makes for really bad readability
and - worse - possibly error prone code.
What to do with scope rules ?
Var
C : integer;
begin
C:=1; // C is integer
// New block, hence new scope
for var c:string in List do begin
... // C is string
end;
Which is IMO error prone.
the alternative is the javascript way, elevate the "c" in the for loop to a
procedure local variable, in which case the above should result in an error,
and which is a major source of problems.
Either way, I don't think this is very desirable.
Michael.
