Tweak some optimizations. Delegates passed to inlined functions now also stand a chance of being inlined. This should make opApply as efficient as a regular loop, as long as both opApply and the foreachbody are eligible for inlining; which is to say most non-virtual opApply invocations will likely get fully inlined now. (Note: above requires -O2 -enable-inlining or -O3)
