XSLT, Perl, Haskell, & a word on language design

[Manuel M. T. Chakravarty]

This article on Kuro5hin should be of interest:

As a text snippet to provoke you to actually follow the link,
I have chosen,

  The really bad thing is that the designers of XSLT [1.0]
  made the language free of side effects but then failed to
  include fundamental support for basic functional
  programming idioms.

Cheers,
