Flay is blowing my mind

No, really. Flay is blowing my mind. It is just getting cooler and cooler. The next version of flay is going to have a verbose mode that will try to show an N-way diff:

Matches found in :when (mass = 84)
  A: unit/itemconfig.rb:182
  B: unit/itemconfig.rb:192
  C: unit/itemconfig.rb:207

A: when /^(#{__item_numstrval_optkeys(tagid(tagOrId)).join("|")})$/ then
B: when /^(#{__item_listval_optkeys(tagid(tagOrId)).join("|")})$/ then
C: when /^(#{__item_strval_optkeys(tagid(tagOrId)).join("|")})$/ then
A:   num_or_str(tk_call_without_enc(*(__item_cget_cmd(tagid(tagOrId)) << "-#{option}")))
B:   simplelist(tk_call_without_enc(*(__item_cget_cmd(tagid(tagOrId)) << "-#{option}")))
C:   _fromUTF8(tk_call_without_enc(*(__item_cget_cmd(tagid(tagOrId)) << "-#{option}")))

And Patrick Ritchie recently submitted additional similarity reporting that I'm going to work on folding in soon. His version allows extra fuzzier matching of copy-pasted code that has been edited!

Soon I will write up why flay kicks towelee, PMD, and everyone else's tool in the ass... But I think the above is a damn good start.
