Is there any reason why
mixin template Foo(T)
{
}
Struct Bar(ailas a)
{
mixin a!int
}
doesn't work?
It gives an error saying that mixin templates are not normal
templates.
I hacked around this by making Bar take an enumeration and then
"static switch"ing on it to select the correct mixin template,
but that makes the set of mixins i can pass it closed.
It needs to be a mixin template because I need to access Bar's this from inside Foo.
