http://d.puremagic.com/issues/show_bug.cgi?id=10452 Summary: CTFE: if(x is null) Error: cannot compare __lambda1 at compile time Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: destructionator gmail.com 11:31:05 PDT --- string foo(bool delegate() bar) { return (bar !is null) ? "0" : "1"; } void main() { enum there = foo(() => true); } test12.d(2): Error: cannot compare __lambda1 at compile time test12.d(7): called from here: foo(bool() { return true; } ) I understand generally not being able to compare pointers in CTFE, but I think is null and !is null should be permitted wherever possible because that's something I do a lot: if(dg is null) return some_default; else return dg(); and it would be cool if it worked in ctfe too.
