          Issue ID: 24792
           Summary: is expression doesn't seem to correctly handle
                    function attributes
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: turkeyman at gmail.com

This shouldn't emit `true`:

alias Fun = void function(int);
pragma(msg, is(Fun : RT function(Args) nothrow @nogc, RT, Args...));

The function pointer Fun should not say it's convertible to a nothrow @nogc
function pointer; because it's not!
