https://issues.dlang.org/show_bug.cgi?id=21692 Issue ID: 21692 Summary: Non-mutable extern(D) scope class instances cannot be created. Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: thomas.bockman gmail.com stackConstD and stackImutD should be allowed in the program below, just like the other combinations. Alternatively, if there is some good reason for this restriction, a better error message is needed, because construction is not modification. extern(C++) class C { } extern(D) class D { } void main() { scope stackConstC = new const(C)(); scope stackConstD = new const(D)(); // Error: cannot modify const expression stackConstD auto gcConstD = new const(D)(); scope stackImutC = new immutable(C)(); scope stackImutD = new immutable(D)(); // Error: cannot modify immutable expression stackImutD auto gcImutD = new immutable(D)(); } --
