      Hi,

      At the page here:

      http://www.julienlecomte.net/yuicompressor/CHANGELOG

      we have:

      > YUI Compressor 2.3.5, 2008-02-08
      >--------------------------------
      >
      > + Added a warning when more than one 'var' statement is used in a single
      > scope.
      > Automatic coalescence is extremely complicated, and would be unsafe if not
      > done properly.

      Can someone explain to me (and the list) why the variable coalescence is so
      complicated?

      Kind regards,
      Jim
