           Version: D2
          Platform: x86

          Severity: enhancement

This enhancement request is almost a bug report.


import std.stdio: writeln;
enum Foo : char { A='a', B='b', C='c' }
void main() {
    const Foo[] foos = [Foo.A];
    writeln(foos);
}



DMD 2.055beta gives errors, but I'd like to print such arrays too:

...\src\phobos\std\format.d(1338): Error: static assert 
(isInputRange!(const(Foo)[])) is false
...\src\phobos\std\format.d(1652):        instantiated from here:
formatValue!(LockingTextWriter,const(Foo[]),immutable(char))
...\src\phobos\std\format.d(309):        instantiated from here:
formatGeneric!(LockingTextWriter,const(Foo[]),immutable(char))
...\src\phobos\std\stdio.d(678):        instantiated from here:
formattedWrite!(LockingTextWriter,immutable(char),const(Foo[]))
...\src\phobos\std\stdio.d(1511):        instantiated from here:
write!(const(Foo[]),char)
test.d(5):        instantiated from here: writeln!(const(Foo[]))

This is not an issue of std.format, is the issue of dmd.

enum Foo : char { A='a' }
ref const(Foo) f(const(Foo)[] arr){ return arr[0]; }
// test.d(2): Error: arr[0u] isn't mutable
