[Haskell-cafe] Most used functions in hackage

[Gwern Branwen]

One thing you could do is download Hackage (easy enough with a little
scripting of 'cabal list'; see for example
http://www.haskell.org/pipermail/haskell-cafe/2011-July/093669.html ),
unpack, and use Language.Haskell.Exts to parse every Haskell file.
Here are two examples from the past:

1. http://www.haskell.org/pipermail/haskell-cafe/2012-January/098618.html
function-name search script which lets you parse a large number of
source files and print out anything calling a specified function (eg.
if you were thinking about deprecating something)
2. http://www.haskell.org/pipermail/haskell-cafe/2011-May/091663.html
language-extension search script; I used it to see how many source
files ever invoked LANGUAGE pragmas and which ones.
