This OTOH is meaning that we can do the check only at runtime. Thus the C<tailcall> or C<tailcallmethod> opcodes have to do plain calls if they detect such a situation.
Yep, although there will be some situations where we can know for sure at compile time--for instance if all function calls within a function are tail calls.
Tail calls should be explicit, compile-time things. Otherwise we're going to run afoul of traceback requirements and suchlike things, and I think that's just not worth the risk and hassle. Besides, it's a lot easier in general for a language compiler to decide when a tail call's in order than it is for us.
