Hi,

sorry for the delay.

I don't really understand what you're trying to do that can't be done
with REAL-NAME and a function designator for PARAMETER-TYPE.  Maybe
you can provide an example?

I'd say that if it can't be done, then your task is probably too
complicated for an "easy" handler, but maybe I'm missing something.
The idea of DEFINE-EASY-HANDLER is that it is a convenience macro for
90% of the handlers one usually writes - the mundane ones.  It was not
intended as a general purpose tool for every conceivable Hunchentoot
handler on Earth.

It is there to check for syntax errors.

That's good to know... :)
