No, in my example they're both references to an object instance - they're simply identifiers. Languages that are case-insensitive tend to force one to use identifiers that are also descriptive as to their usage, which is very helpful when reading code as you can tell a type from a variable from a.... Re: languages: Pascal/Object Pascal is case-insensitive, and is statically-typed. Re: SQL: all implementations that I'm aware of use case-insensitive identifiers for all of the reasons that I've outlined. Any that don't are problematic, at best. Re: locales: the way that this is typically handled is by a) restricting the allowed characters to the English alphabet (older), or b) by using Unicode (UTF-16) encoding for source files (newer).
