 You misquote me.  It's not a lack of flexibility of regular expressions;
 it's the requirement to match each URL in it's entirety that makes it very
 difficult for most people to set URL routes for anything beyond trivial.

 Remember the old saw:

    ''"I had a programming problem and decided to use regular expressions.
 Then I had two problems."''

 segments - this can already be done
 ([http://wordpress.stackexchange.com/questions/9419/remove-taxonomy-slug-
 from-a-custom-hierarchical-taxonomy-permalink/9685#9685 one example]) - it
 shouldn't be the main way of defining rewrite paths.

 regex rules.

 Can you please explain the logic behind your conclusion and why it makes
 sense to continue to flatten a tree structure for matching?  Also please
 address the subsequent duplication required to match similar leaf nodes
 (like permastructs) rather than to match a tree structure using a tree
 structure, as proposed?

 Also, can you help me understand why you'd advocate maintaining a system
 that generates and map upwards of 1000 regular expresssions for a complex
 CMS when with a tree structure the matching would be 1 to 2 orders of
 magnitude less per page load?

 And please address why retaining the complexity of the regular expressions
 as used in the rewrite system makes sense vs. much more straightforward
 simple match rules that mere mortals are much more likely to understand
 (with fallback to RegEx, of course?)
