Description

Automatic conversion of arguments to variadic argument functions into Variant should be possible (Boxer has it).

DRK in #676:

Agreed. I've just never gotten around to writing it, since I've never needed it. I will likely get around to 3. eventually, just haven't had time as of yet.

All that is really needed is a constructor for Variant that takes a void* and a TypeInfo?. It shouldn't be too difficult.

For reference, I've created a Variant type that has such a constructor: http://dsource.org/projects/dmocks/browser/reflect/reflect/variant.d with tests: http://dsource.org/projects/dmocks/browser/dunit/trunk/tests/variant.d

Added patch to resolve ticket. I'm waiting to be able to test under GDC and LDC.

GDC doesn't appear to have support for vararg (va_arg appears to be stubbed out) and LDC's implementation looks to be a compiler intrinsic.
