why: using function stubs made it possible to check the syntax of an op handler source file by compiling this very file. this was previously impossible due cyclic import/include mechanism. details: only oph_call.nim, oph_create.nim and subsequently op_handlers.nim still need the -d:kludge:1 flag for syntax check compiling. this flag also works with interpreter_dispatch.nim which imports op_handlers.nim.
