String Replace Problem...

[Sean McIlroy]

Alright, now it's too much. It's not enough that you're eliminating it
from the language, you have to stigmatize the lambda as well. You
should take some time to reflect that not everybody thinks the same
way. Those of us who are mathematically inclined like the lambda
because it fits in well with the way we already think. And besides, it
amounts to an explicit declaration that the function in question has
no side effects. And besides, it adds flexibility to the language. Go
ahead and throw it away, but you're making python less accessible for
those of us whose central concern is something other than programming.
