ghc api / calling functions?

[Maarten]

Dear all,

Is there a way to use the ghc api to call functions directly instead of 
evaluating statements (more or less similar to hs-plugins)?

So far, thanks to some info pages, I have been able to load sessions and 
make modules, however there seems to be little or no documentation on 
calling functions directly. Any info/pointers appreciated. Thanks.

Kind regards,

Maarten
