Strongly disagree. We have style guides because the language allows many things which are not good code. Given that Python programmers can't decide on whether the line limit should be 79, 80, 100, 120, or "79 but you can stretch to 100 if you have to", what should the syntax be coded to? It's just as bad style to produce a 500-character line as it is to abuse operator chaining, so should we take our complaints about over-long lines to "whoever didn't put a length limit into language syntax"? What about indenting with 5 spaces - should that have been disallowed at the language level? And what about misspelled comments - obviously they're bad style, so clearly Python should raise SyntaxError any time it comes across one, right? No. The language should be kept simple, and on matters of style, it should have MORE flexibility than we use - otherwise it's a straitjacket. ChrisA
