ridiculously easy to experiment with this. Want to see what it's like to
use "en" or "ix" or whatever instead of enumerate? Just do "en =
enumerate", and you can start using it. See how it affects your typing
speed, and the readability of your code. (Obviously it will make your code
less readable to the general Python community, but ignore that; the
interesting question is whether you--or, better, a small group you work
in--find it readable once you get used to it).

I can pass print to a function instead of having to write an out-of-line
wrapper with def. I can do quick joining without spaces, and no-newline-ing
without having to mess with magic commas. But then, like most of the others
who prefer print as a function, I don't actually use it nearly as much as
the people who are complaining, so maybe that doesn't mean much.

A few months ago I came up with a working "call statement" implementation
that would allow the parens to be omitted from all simple calls, not just
print: http://bugs.python.org/issue18788

That shows such an approach is technically feasible, but it also makes it
clear there are major readability issues if the LHS is allowed to be an
arbitrary expression.

I'm still vaguely curious what a full PEP for 3.5 (with a suitably
constrained LHS) might look like, but I'm not interested enough to write it
myself.

Cheers,
Nick.
