Comment #2 on issue 240 by vogt.adam: recompilation fails silently
http://code.google.com/p/xmonad/issues/detail?id=240

The attached code uses haskell-src-exts to grab the module name and throws  
a warning
when it isn't main (no module name is implicitly main).

It might be better to use the ghc-api for the parsing (since  
haskell-src-exts rejects
more programs than ghc does)

This adds a pretty serious dependency, so as-is this code cannot go into  
core.

A better way might be to check after the compilation that there is actually  
a
generated binary.

This issue is somewhat related to the suggestion for keeping ghc's temp  
files out of
~/.xmonad/
