          Issue ID: 21898
           Summary: Qualifier ignored in alias definition if parentheses
                    are not present
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dlang.org
          Assignee: nobody at puremagic.com
          Reporter: andrei at erdani.com

Consider:

alias Works(T) = immutable(T);
alias Fails(T) = immutable T;

static assert(is(Works!int == immutable int));
static assert(is(Fails!int == immutable int));

The first static assert passes, the second doesn't. Both should.
