          Issue ID: 21017
           Summary: Tuple fails with inout and -allinst
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: uplink.coder at gmail.com

The following code will cause the compiler to ICE, when compiled with -allinst.

import std.typecons : Tuple;

pragma(msg, is(Tuple!(inout int)));

This is due to an erroneous function definition surviving until
code-generation.

Opened in Phobos and not in DMD since it can be workaround in Phobos.
