I hate to point out the obvious, but...

in Delphi, to clarify your call you simply do the
following:
p(integer(f));
it will call procedure "procedure p(i:
integer);"
if you do
p(f)
it will call procedure "procedure p(f : tf);"
You have the best type-checking if you don't convert
to a pointer using @. Unless of course you've
proposed changing the normal behaviour of the @
operator so some kind of type-checking is done with
function and procedure types??
BTW, I now have Linux up and running on my system and
I can dial into the 'net too so I will be doing some
Lazarus development work soon...
Kevin.
