In the beginning, there was DTML.  DTML did not have expressions as was
designed to look very much like HTML, so names like sequence-item were
chosen.  Later on, expressions were added.  Names like 'sequence-item'
were obviously not going to do, because in a python expression it looks
like a subtraction.  So, the DTML namespace was given the name _, and
given a mapping interface which allowed you to look up names in the
namespace.  Thus was born _['sequence-item'].  _ is a mapping like any
other.

It's really not that bad, just kinda ugly.
