Wow, the "online help utility" for 3.1 looks really useful and
informative. One question. Many of the articles are LONG. When I've
got what wanted out of one, I want to quit, but don't know how to quit
More. How to?
Another is, although I've seen this before in older Python docs, I
never really understood things like
for_stmt ::= "for" target_list "in" expression_list ":" suite
["else" ":" suite]
no Python documentation found for '::='
In particular, what exactly does "::=" mean?
