Fortunately no one but you have even suggested the "plain application of
regular expressions".  But if you are referring to what I wrote about
using PHP's PCREs then you are wrong.  There are simple non-regular
markup schemes that can be handled very simply with preg_replace_callback.
That remains true even if you force the use of the the strictly regular
subset of patterns because of the power gained from the callback.  The
non-regularity of the markup is not the key deciding point.  I'd give
you an example but I am hoping that by quoting in full you won't waste
your precious time commenting on this.
