No fair Emile -- the spec in the subject DOES mention a
name-binding IS part of the requirement!  The fact that
you don't need a space in '1for' is very interesting, and
surely boosts Python in the esteem of all developers who
are keenly aware that a language's only reason for being
is minimizing keystrokes (why call the result 'ans' when
'_' would do just as well, btw?!) -- but the fact that
the requested name rebinding doesn't seem to be serving
any actual purpose is NOT one we're supposed to notice!
