Hi Samuel,
yes, a general Lisp syntax is certainly a good idea. In fact,
currently the match is also converted into a Lisp form. However, it
does not use simple variables that would be great to supply in a user
form. The reason is that I am trying to minimize parsing for
properties and tags, so that these are only located if used. Still, I
guess you are right that this is a relatively simple extension to make
- I will think about it.
- Carsten
