https://issues.dlang.org/show_bug.cgi?id=21269 Issue ID: 21269 Summary: ReplaceType on function type does not compile with -betterC Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: snarwin+bugzilla gmail.com Example: --- import std.typecons: ReplaceType; alias F = ReplaceType!(int, double, int function()); --- Compiler output: --- /dlang/dmd/linux/bin64/../../src/phobos/std/typecons.d(8958): Error: TypeInfo cannot be used with -betterC --- The cause of this error is the private helper template replaceTypeInFunctionTypeUnless, which uses the `~=` operator in CTFE. Due to issue 19268, this causes compilation to fail. --
