[fpc-pascal] Use a procedural type for declare a procedure\function

[Andrey M, Zubarev]

Hi All,

Why can't use procedural type for declare a procedure\function?
Why ever allow the exact same signature? It's uncomfortable
Maybe it makes sense to introduce into the language such a possibility?
For example such code:
[code]
type TMyCommand=function(arg1:TMyArg):TMyCommandResult
begin
...
end;
function command1(arg1:TMyArg):TMyCommandResult;
begin
...
end;
function command2(arg1:TMyArg):TMyCommandResult;
begin
...
end;
function command100500(arg1:TMyArg):TMyCommandResult;
begin
...
end;
var
...
com:TMyCommand;
...
com:=GetNeededCommand;
res:=com(arg1:TMyArg)
[/code]

Could look like this

[code]
type TMyCommand=function(arg1:TMyArg):TMyCommandResult
begin
...
end;
command1 TMyCommand;
begin
...
end;
command2 TMyCommand;
begin
...
end;
command100500 TMyCommand;
begin
...
end;
...
var
com:TMyCommand;
..
com:=GetNeededCommand;
res:=com(arg1:TMyArg)
[/code]
