I capitalise my globals/Fields and locals are lowercase and some terms, like "id" I'd like to be able to re-use locally. But it's not a big issue for me - and of course completely style-related.
This is what we call a bad practice.Secondly, this is BASIC, whether you like it or not. The amount of people who think case-sensitivity is worthless is likely to far exceed the number who think it has even the remotest benefits. Secondly, to address the idea of it being good for beginners, I don't see how pissing off the beginners is a good idea, regardless of whether or not they learn to type like something other than a chimp. Also, David's example even provides a reason some people give that is very, very bad. Ambiguity between names when the only difference is case is not going to help anyone, and certainly not the beginners.
If you can't type the way you want to type only because of your own errors, that's your problem, not the compilers.
