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
