But whatever solution you come up with, please make it compatible with the notion that "aardvark".."apple" can be used to match any word in the dictionary that comes between those two words. > I've never accepted that the range between two strings of identical length > should include strings of another length.

This is why I dislike the notion of the range operator being used to produce lists: the question of what values you'd get by iterating from one string value to another is _very_ different from the question of what string values qualify as being between the two. The more you use infix:<..> to produce lists, the more likely you are to conflate lists with ranges. -- Jonathan "Dataweaver" LangThread Previous | Thread Next
