Comment (by tscrim):
Replying to [comment:211 stumpc5]:
> Travis: Also, you introduced {{{_reduced_word}}} to be a lazy attribute.
This has a few drawbacks: {{{not self._reduced_word is None}}} in the
length function in {{{reflection_group_real.py}}} is never triggered, and
{{{_reduced_word}}} is now either a word in the index set (if the lazy
attribute is triggered in the real case), or a word in {{{range(n)}}} if
one has gotten it through the iterator. This way, the method
{{{reduced_word}}} in the real case is always executed, even though the
reduced word is already known.
Trac is being stupid. Message to be edited...
