Unfortunately the current incarnations of hasktags do not generate
tags files that vim likes much. Workarounds are to use ghci 6.6's :tags
command, or to sort the generated tags files afterwards. Another
gotcha: hasktags generates the files 'tags' and 'TAGS' by default. This
*will* break on case-insensitive file systems such as e.g. default  
installations
of HFS+ on Macs.

Doei, Arthur.
