| 2. Calling from foreign code into Haskell to a bound foreign import
will
| require some special handling to ensure that a subsequent call out to
| foreign code will use the same native thread. Why couldn't this
special
| handling select the same Haskell thread instead of creating a new one?
Any chance :info could also report fixity information, especially for
symbolic identifiers?

I've postponed writing up a new proposal again...
But I'm going to sum up some requirements that I would like to see
fulfilled - to make it clearer to others why I'm proposing such strange
things...

that is what Concurrent is for, Haskell threads, (well GHC threads) are

It seems also a good summary of everything haskell-related :) Thanks, it
is useful to me.

Can I safely translate that as We use design patterns but we don't
like the name?

The virtue, and weakness, of traditional design patterns is their
