Currently, I am using expressions like
for s in positions])
Once I have iterator expressions, I can simplify it by dropping a whole two
characters (the brackets) and get an unimportant time savings. But with
PEP 274, I could write
for s in positions}
Instead of five levels of nested parens+brackets, I would need only three,
and each level would be a different type of paren or bracket, which I think
together with the shorter overall length would contribute significantly to
