Did you ever run into that bug in IOS where if you had `ip as-path
access-list 1 permit ^(1|2|3)+_$' (where 2 and 3 would be customers of
AS1 who is one of your peers), and the third number is higher than the
second number?  IOS seemed to optimise that case out and reject AS paths
of ^1_2$ if the filter was written as ^(1|3|2)+_$.

This was several years ago though.
