FWIW I agree with . I've worked for the last quarter century as a programmer in the UK and the Netherlands, mostly using Microsoft technologies. The usage I'm familiar with treats camelCase and PascalCase as being distinct. So perhaps in a broader context, camelCase encompasses both, but when two programmers are communicating with each other, the ambiguity would just be unhelpful. "What's the coding convention for fields on this project?" - "Oh, we use camel case" - "What, you mean camel case camel case, or pascal case camel case?". I understand that my personal experience probably doesn't meet the guidelines, but I'm convinced that the usage I describe is widespread, and I hope this is enough to establish at least some doubt about the sweeping definition given in the article as it stands. Maybe that Microsoft Capitalization Styles document is authoritative?
