Not yet. We have to clean up the internal_exception stuff first. C<find_lex> could e.g. return a NULL in case of failure, and we could then throw an exception in F<var.ops> at the opcode-level, so that the exception would be resumable. > 2) What about a "search_lex" op that follows the format of > "find_lex" but which stores null in the target PMC register > (Px).
