Goddamnnit, what the fuck is wrong with me? Yes that works :)
I suspect a better error message would have prevented this.
DMD still has some potential of improvement in that area. =)
In that case, to!(Origin, Target) could be extended to deal with
to!(Origin,<empty there>).
It's been a long time since I last looked at std.conv.to, but maybe:
template to(T)
{
T to(A...)(A args)
{
static if (A.length)
return toImpl!T(args);
else
static assert(false, "Trying to use to!("~T.stringof~")
with no argument. What were you trying to do?");
}
}
The compiler should be able to give you a better error message. It
shouldn't be the responsibility of the programmer to provide sensible
error messages when you call a function with the wrong number of arguments.
