Summary: Allow forward referencing IFTI types in template argument list Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: thecybersha...@gmail.com --- Comment #0 from Vladimir Panteleev <thecybersha...@gmail.com> 2014-03-21 20:17:57 EET --- Consider this hypothetical example: ///////////////// test.d ///////////////// T[] copyArray(T=I, I)(I[] input) { auto result = new T[input.length]; foreach (n, ref i; input) result[n] = i; return result; } void main() { // copy as is int[] r1 = copyArray([1, 2, 3]); // copy to another type long[] r2 = copyArray!long([1, 2, 3]); } ////////////////////////////////////////// There is currently no way to get this code to work, without either declaring an overload for copyArray, or replacing T=I with T=SomeDummyType and later checking to see if something was explicitly passed or not. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
