http://d.puremagic.com/issues/show_bug.cgi?id=6852 Summary: Cannot compare instances of ParameterStorageClassTuple Product: D Version: D2 Platform: Other OS/Version: Windows Status: NEW Severity: major Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: andrej.mitrovich gmail.com 09:43:42 PDT --- import std.traits; void test(T1, T2)(T1 t1, T2 t2) { alias ParameterTypeTuple Types; static assert(is(Types!T1 == Types!T2)); // ok alias ParameterStorageClassTuple Stores; static assert(Stores!(t1) == Stores!(t2)); // NG static assert(Stores!T1 == Stores!T2); // NG static assert(is(Stores!t1 == Stores!t2)); // NG static assert(is(Stores!T1 == Stores!T2)); // NG } void main() { test( (int){}, (int){}); } What gives? ParameterTypeTuple doesn't suffer from these issues. It seems it's impossible to compare equality of storage classes between two functions. :s -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

From 2.063, value tuple comparison would work by fixing issue 9873. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
