[Haskell] Force evaluation

[Michael Walter]

Hi,

is there a way to force the "full" evaluation of a value (unless seq,
which only brings the term to WHNF)?

In my case, I have an algebraic data type Foo,
and I would like to catch the exceptions that will occur during the
evaluation of a value of Foo, for something like:

  foo <- force makeFoo `catch` \e -> defaultFoo

Thanks,
Michael
