Hi!
I've been thinking about how alias template parameters work and
I'm really confused =)
It makes perfect sense for literals, names, etc. But what I
can't get is how does it work for delegates.
If I have a function
auto apply(alias fun, T...)(T args)
{
return fun(args);
}
And then I have
int y = 2;
apply!(x => y)(1);
How in the world does this work? Is the context address known
at compile-time?
y is allocated on the heap and the pointer is implicitly passed
to the apply, or is a field of a struct if you use map!(x => y)
instead.
