What do you mostly use for debugging?

I also wonder about 'type-debugging'
Using ghci:
For a top level expression:
- if it is not compiling I can put in (or remove) a
But for internal expressions it can be quite hairy to figure out why what
haskell thinks is the type of something and what I think dont match.
^^ Just give the internal expression a type you know to be wrong, then GHC
will display the infered type and say it doesn't match the one you wrote.

Debug.Trace, with some short helpers

dbg msg x = dbgsh show msg x
dbgsh
