[Haskell-cafe] Using _ on the RHS of an equation?

[Paul Keir]

Hi Jason,

I like the idea. I've seen some code from Oleg Kiselyov which
uses __ (two underscores) in this way.

The thing that stops me though, is when I get it wrong, and
undefined fires somewhere, but I don't know where. Something
like you propose, but with a line number, would be sweet.
