Re: Proposal: Add (&) to Data.Function

And the results of the IRC discussion on lens: https://github.com/ekmett/lens/issues/100 I do think that this looks nicer, for whatever reason. While the mnemonic of "mod"ulus can suggest modify once you know that, (&) somewhat naturally suggests "and then" ... "and then". I still prefer (#) for overall consistency and history, but other than its conjunction connotations, (&) is mnemonically better. It'll be funny to mix diagrams and lens code - (&) is used for sticking coordinates together for points / vectors - while (#) would stand in for (&).

(#) is also used by the diagrams library, mainly for using functions as if they were "attributes".

In the context of lens, this is discussed a bit here: https://github.com/ekmett/lens/issues/17

"Haskell" called this operator (#) about 12 years ago - see Peter Thiemann's WASH and Eric Meijer and colleagues MS Agent scripting.

I'd much prefer (#) if it didn't interfere with GHC's magic hash, I suspect the above authors were using Hugs...
