[Haskell-beginners] Memory usage prediction

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:


The only caveat is you have to reinstall your libraries with profiling

(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.)
