           Summary: Function attribute inference fails in case of mutual
                    dependencies
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: timon.gehr gmx.ch

Tested with DMD 2.057.

void foo()(){bar();}
void bar()(){foo();}
void qux()  safe pure nothrow{foo();}

Error: pure function 'qux' cannot call impure function 'foo'
Error: safe function 'qux' cannot call system function 'foo'
Error: foo is not nothrow
Error: function tt.qux 'qux' is nothrow yet may throw

The code should compile.

Apparently the spec has been changed to document the buggy behaviour.

function.html:
"Cyclic functions (i.e. functions that wind up directly or indirectly calling
themselves) are inferred as being impure, throwing, and  system."

Therefore this is now both a spec and a compiler bug.
