And of course, at that point, you'd be better off just writing the script in Haskell.
I'd still be happy if cabal better supported heterogeneous projects, where some parts are written in another language. Count it as my feature request - seems to be be quite easy as far as executable installation is concerned. There are many reasons to write some utilities in another language, like * legacy code * a two-liner shell script is small, where an equivalent compiled haskell code may be hundreds of kbs (looks like cabal doesn't allow to install haskell scripts, only compiled code) * my editor does syntax highlighting for pure shell scripts but not for shell scripts wrapped in haskell * love for pipes, subshells, perl regular expressions, etc. If you want an example, look at ghc: it comes with perl scripts.
