[Haskell-cafe] Fwd: Improving 'project'

[Justin Bailey]

My apologies for the cryptic email below - I meant it for the
haskell-db users list. And now I have to apologize for this spam too.
Should I send yet another email? ;)

All,

project doesn't easily let me add a few columns to an existing query
(or take a few columns away). Instead, each use of project requires me
to build the entire list of columns I'd like to pass on by hand.
Before I go further, if there is a way to do that, please let me know.
