struct VeryLargeType { static foreach (i; 500.iota) { mixin(format!"int v%s;"(i)); } } unittest { VeryLargeType a, b; move(a, b); } Result: std/traits.d(2848): Error: template instance `std.traits.RepresentationTypeTuple!(VeryLargeType).Impl!(int, int, int)` recursive expansion Expected: not that.

@FeepingCreature created dlang/phobos pull request #6873 "Fix issue 19689: don't use recursive template parameter iteration in std.traits." fixing this issue: - Fix issue 19689: don't use recursive template parameter iteration in std.traits. Pull inner Impl templates out into std.traits so they're only instantiated once. Use anySatisfy, staticMap instead of manually recursing. https://github.com/dlang/phobos/pull/6873
