I'll make sure to respond right away in future, before I've fully understood the subtleties and implications of your replies. :D
I was digesting the reply. I've been neck deep in developing a USB keyboard solution for the QL - a project that has become a multi-headed beast that required getting into elements of the 8302/8049 relationship I just never knew I'd have to think about. Also neck deep in fence building after a neigborhood dog broke into the pen and killed many of my chickens. It does seem that coercion gives similar results - if everything is passed as a string, it can be coerced however we'd like, as long as the data is checked for validity. It does seem the functionality of overloading can be implemented in roundabout yet still brief and readable ways. Thank you.
