I'm not sure such a thing is good... At the very least, such reviews
should be anonymous, especially if we're going to cover bad code
instead of good. Here's my contribution:
I was cabalizing a package once, and I chucked into the build-depends
'ghc' and made it build. About 30 seconds later, it occurred to me
that this was a geometry library and what the heck was it doing with
the GHC API? So I go looking, and I find a module of utility
functions. It's importing GHC.Base.
I remove the import and scroll down to see the error.
It turns out that 20 megabytes of GHC code was being linked into this
program for one function.
I took the quick way out and typed into the module: 'isJust Nothing =
False; isJust (Just a) = True'.
