If you want to treat 1 and -1 as the same, you filter through abs().
If you want to treat a and A as the same, you filter through lc().

In neither case do you go creating new functions, when a generic
filter will suffice.  It's like making all programs understand some
random new switch rather than creating one single filter program
that produces the proper transmogrification.  It's the Wrong Way.

And you certainly don't go creating a brand new syntax!
