Also the -Wall switch for GCC throws many warnings in Core package, some of them can be easily fixed (like for example:
C:\upp\uppsrc/Core/Parser.h:2: warning: suggest parentheses around && within ||

Sorry. I am not gonna to fix this. I am no slave of some idiot who does not remember that && has higher priority than || and thus adds such idiotic warning.

What will be next? What about (x * y) + 10?

The whole purpose of operator priorities is to reduce the number of parenthesis. Do you really think this code is more readable

return ((c >= 'a') && (c <= 'z')) || ((c >= 'A') && (c <= 'Z')) || (c == '_');

??

Actually, I'm one of those idiots, and I prefer exactly that return like you wrote it. Smile

I have 2 reasons to do so... from my historic experience I don't believe compilers (it's not like I hit a bug in them every month or so, actually probably less than 1 bug per year, but it made my faith gone), and for me it's easier to "parse" parentheses in head, than to think about interaction between operators, as the parentheses is one *single* rule, and there are *many* operators. I got so far that in my source I already see ((a * b) + c); Razz

Very Happy

edit: but this is the least important "problem" from those I reported. Smile

Look rather at that weird LanguageInfo without return issue.
