           Summary: compile time evaluation with invariant problem
           Product: D
           Version: 2.006
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: braddr puremagic.com


This compiles:
template foo(A...) { invariant char[] foo = A[0]; }
static assert(foo!("a") == "a");

This doesnt:
template foo(A...) { invariant(char)[] foo = A[0]; }
static assert(foo!("a") == "a");

The error: static assert  (foo == "a") is not evaluatable at compile time

the difference is the ()'s around char, it's subtle. :)

The compiler doesn't give the normal 'invariant is deprecated' error message
for the first case. I think it's not running semantic() on it.
