typeid reversing ?

[Daniel919]

Hi,
just had some thoughts about casting and types.

--------------------------------
import std.string;
import std.stdio;

void giveparam(int a) {
    writefln("takeparam " ~ format(a));
}

void variadic( ... ) {
    if(_arguments[0] == typeid(int))
    giveparam(* cast(int *) _argptr);
    //else if(_arguments[0] == typeid(double))
    //... and so on
}
/*
given......................: _arguments[0]      == typeid(int)
if this would be possible..: ???(_arguments[0]) == int;

I could write giveparam like this:
giveparam(* cast(???(_arguments[0]) *) _argptr);

and would not be forced to do if-checking for all types
*/

void main() {
    variadic(1);
}
---------------------------------------

Is there a way to do this ? If not, could something like this be integrated
to D ?


Thanks for your replies in advance.
