I can see adding the 1-argument form to operator or functools (as it's useful in functional programming), but the 2-argument form you've suggested is right out. If you really feel the need to torture a "for" loop into a genexp/listcomp like that,

foo = (x for x in bar if condition(x) and [memoize(x)])

does the same thing using today's capabilities.
