This could be made compatible with the FPC handling of Body, where
e.g. a program or a procedure body is a Body, parsed by
tcgprocinfo.parse_body().
The only required parser modification had to treat a For statement as
a Body, with an (optional) specialized Var section at its begin, and a
Statement after Do.
But this solution would look strange to C coders, which expect
variable declarations *after* the begin of an block, while Pascal
expects local variables declared *before* the begin of an block. OTOH
I don't think that it would be a big deal to allow for Pascal
declarations also at the begin of an block. The syntax would look like:
Block = "BEGIN" [Declarations] {Statement} "END" .

This already help, but what about declaring also after some code?
I like on Java/C++/PHP that I can create a for-loop that creates the
counter... sample on PHP:
for(var; condition; step) for($var=0; $var<1000; $var += 1)
This syntaxe is possible on C++, Java (its not equal, but its something
very close).
I would like to be able this:
[ some code after begin ]
DoSomething;
var I: Integer;
for I := 0 to 1000 do
DoAnotherThing(I);
[ inside the code ]
