Problem with Variant

2013-06-28 Thread develop32 

void main()
{
struct Vector
{
float length();
}

import std.variant;
Variant v = Vector();
}

Currently this does not work, as it seems Variant thinks length() 
is a property restricted to arrays.


"cannot implicitly convert expression ((*zis).length()) of type 
float to int	C:\D\dmd2\src\phobos\std\variant.d	488"


I quickly changed that line in variant.do to "static if 
(is(typeof(zis.length)) && is(ReturnType!(zis.length) == 
size_t))" and my code compiles.


Currently its a hack, but should it be more developed and would 
it not interfere with something else?

Well, he can do that in an _imperfect_ world too... ;)
