[Haskell-cafe] SoC idea: interactive profiling

[Peter Verswyvelen]

yep, sounds great to me :-)
although with some hacks one can already have a poor mans real time
interface for heap profiling:
http://www.haskell.org/ghc/docs/latest/html/users_guide/hp2ps.html#id2677301

I agree that the effect of laziness can be very hard to grasp, sometimes it
even feels that I traded the annoying side effects from imperative
programming to "lazy effects" in functional programming... Can't seem to
have my cake and lazily eat it :-)
