I get the clear documentation part, but I'm not sure how raising an error for non-integer arguments would be consistent -- the built-in routines I've checked don't seem to, and ListExt routines don't either. So what would that be consistent with? Or are you referring to non-numeric arguments (as opposed non-integer)? Those should definitely raise errors in my opinion.

Sorry, I clarify. If for my library I decide that I accept only integers as subscripts and I state it properly, then I keep doing this (unless otherwise stated for some particular commands).

It does not matter, for me, that the built in commands accept also decimals, the library should be consistent with its documentation, not (necessarily) with other commands, built in or popular.

So I would be completely ok if you say "look, please provide integers or reals without decimal parts".

I actually don't know why GET and SUB would work with reals with decimal part. It can surely produce some nice "tricks" but looks dirty in my opinion.

edit: I'll do the "processing strings!" thread. I need to find the proper set of challenges though (the start should be small but interesting) I will think about it.
