The short answer is no. This is Haskell's biggest weakness: it's difficult
to predict space usage.
The longer answer is "kind of" -- you can't exactly intuit it, but the
profiler is easy to use:
http://book.realworldhaskell.org/read/profiling-and-optimization.html
http://www.haskell.org/ghc/docs/7.6.2/html/users_guide/prof-heap.html
The only caveat is you have to reinstall your libraries with profiling
enabled:

(If I've already installed some packages, usually I take the quick and
dirty route and just set library-profiling to True, delete ~/.ghc to clear
the package list, then install my package.)

Hi,
Where can I find some informations abut memory usage prediction? In C (or C++) while I write code I can predict how much stack space will be used, how much heap space will be used, I can count instructions. I want to see all these things while I'm looking at my code. Is it possible in Haskell?
Best regards, Emanuel
