[Python-Dev] Re: Boundaries between numbers and identifiers

I feel like all of these examples, if found in the wild, are far more likely to be uncaught bugs than programmer intent. Being strict about spaces (or parents, brackets, etc. in other contexts) around numbers is much more straightforward than a number of edge cases where is not obvious what will happen.

[0x1for x in (1,2)] [31]

It is parsed as [0x1f or x in (1,2)] instead of [0x1 for x in (1,2)].

That’s a wonderfully terrible example! Who’s maintaining the list? :D
