The patch needs some rework before it can be accepted. First, I'd prefer to avoid the duplication of code between the get_integer and get_number vtable functions; better would be put the logic into the .elems method, and then have the vtable functions get the results from .elems instead of vice-versa. Second, I'd like .elems to be able to figure out the size of the range without having to generate the full list and take the size of that. (That might not be easy to manage, so I'll accept an interim patch that builds the list for now if that's all we can do.) Third, note that the get_string vtable function can't really return a !FAIL, because it's constrained to return only native strings (which can't hold a Failure object). So that probably needs some rework. So, work on those a bit and resubmit. Thanks! Pm
