know about this. It has already been mentioned by Taylor Hedberg.
And as correctly observed by Taylor, one does not simply walk into
Mord^W^W^Wpull in lens just to get a simple function that you can
define yourself without much trouble. I assumed this thread was about
how people felt about having a backward application operator in prelude.

And I would like to repeat my argument that '<|' and '|>' are much
nicer mnemonically than '$' and '&'. (Though Edward has made the case
for '&' being read "and", I don't think that's very nice. He certainly
can't make the opposite case for '$'.)
