Discussion: Can we make evaluate easier to find?

[John Lato]

AKAIK neither one is necessarily safe. You need something like deepseq to
fully evaluate the lazy structure.

If you are sure that evaluation to WHNF is sufficient for performing all
lazy IO, then I think either evaluate or ($!) will work.

evaluate is probably to be preferred if IO is available, similar to throw
vs throwIO.  However I think idioms with seq and ($!) are so common that
they need to be supported too. After all, you may have just a 'Monad m'
context.
