In the following program, the output does not contain "SomeClass". Is

Maybe yes, as a workaround this works:
module main;
import std.stdio;
template Test()
{
enum Test = q{
class SomeClass {
int n = 123;
}
};
}
mixin(Test!());
void main() {
auto sc = new SomeClass;
writeln(sc.n);
foreach(m; ModuleInfo)
{
foreach(c; m.localClasses())
{
writeln(c.name);
}
}
}
Btw. you can use just template, IIRC there is no difference between
template and mixin template
Hey, thanks for the q{} trick. I knew I had seen it somewhere... but
couldn't find it.
That trick only really helps when there is minimal concatenation going
on though. When you have to splice a bunch of stuff together, a
TokenString doesn't provide much relief.
Docs for template mixins explicitly support the behaviour that I'm
after, so I'm gonna file a bug.
" TemplateMixin takes an arbitrary set of declarations from the body of
a TemplateDeclaration and inserts them into the current context."
Yes, thats true. It is a bug. But I just try to say you can omit mixin
word in template declaration. Because it doesn't have any effect.
