The different behavior of is() from bug 7868 depending on whether it was
invoked from a static if condition or not might be acceptable, but this example
is clearly a regression in my eyes:
---
module a;
struct A {
import b : c;
// Instantiate template which uses derivedMembers.
alias D!A Test;
// Unrelated template from other module - �not defined�.
static if (c!()()) {}
}
// Just something using derivedMembers.
template D(T) {
mixin({
foreach (name; __traits(derivedMembers, T)) {}
return "";
}());
}
---
---
module b;
bool c()() { return true; }
---
It compiled fine in DMD 2.058, but fails with �template instance c!() template
'c' is not defined, did you mean a?� in latest Git master (7c22b8a), which is
absolutely not related to the cause of the error.
