Bug 21347 – std.functional.adjoin should work in BetterC

Example program: --- extern(C) int main() { import std.functional: adjoin; alias f = (int n) => n + 1; alias g = (int n) => n + 2; alias h = (int n) => n + 3; alias i = (int n) => n + 4; auto result = adjoin!(f, g, h, i)(0); assert(result[0] == 1); assert(result[1] == 2); assert(result[2] == 3); assert(result[3] == 4); return 0; } --- Compiler output: --- $ dmd -betterC bug.d /usr/include/dmd/phobos/std/array.d(3243): Error: TypeInfo cannot be used with -betterC $ dmd --version DMD64 D Compiler v2.094.0 --- Note that due to details of the current implementation, only calls to adjoin with 4 or more template arguments are affected as of Phobos 2.094.0.
