[Issue 5941] Using inner struct which references nested function in a no-attribute or auto-return member function causes nested function cannot be accessed error
https://issues.dlang.org/show_bug.cgi?id=5941 Kenji Hara k.hara...@gmail.com changed: What|Removed |Added Status|NEW |RESOLVED Resolution|--- |WORKSFORME --- Comment #6 from Kenji Hara k.hara...@gmail.com --- (In reply to Maksim Zholudev from comment #5) Is this behavior correct? Currently it's correct. A nested struct is not constructible outside of the defined function, because it needs valid enclosing context. I think the original attribute-dependent issue is fixed. --

[Issue 5941] Using inner struct which references nested function in a no-attribute or auto-return member function causes nested function cannot be accessed error
http://d.puremagic.com/issues/show_bug.cgi?id=5941 yebblies yebbl...@gmail.com changed: What|Removed |Added CC||yebbl...@gmail.com --- Comment #4 from yebblies yebbl...@gmail.com 2012-01-19 14:04:52 EST --- In case anyone's wondering about why adding attributes changes anything, the compiler does a scan of all the top level members in a nested struct to determine if it contains any functions, and makes it a static struct otherwise. This is unfortunately done badly/too early and it finds AttributeDeclarations containing functions but doesn't investigate further. Given that, it sounds like the requirement for having no attributes is really just a requirement for a non-static nested struct. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Reduced test case suggests it's related to typeof():
auto fx() {
struct S {
void get() {}
}
return S.init;
}
void main() {
//auto w = fx(); // OK
typeof(fx()) z; // fails!
}
Again, adding any attributes to get() removes the bug -- even though get() is
never used.

However, the fact that it compiles if the function 'get' is removed, or if attributes are added to get(), is surely a bug. Based on Walter's comment, it should never compile. So I'm marking as accepts-invalid. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

A slight variant is when 'f' is a template function taking a delegate literal
as input, it will generate an ICE:
-
auto f(alias T)() {
static void h(){}
struct S {
void get() {
h();
}
}
return S();
}
void main() {
typeof(f!((){})()) z;
}
