Slow it is probable, if it is as slow as ruby (see my factorial mail). but
why inelegant? i think it is a very elegant thing to integrate a language
with an application (excel) (<= maybe i am really growing old :-) but still
i think that is a great idea)

as i said before, no problem with the library - have all the necessary books
on my shelf

maybe i should really beginn learning c...
look how good i am already:
#define bah (unsigned double *)(&(--x)++.h->h?x:y) ~= 0815

??? maybe its the inbreeding but i am confused... the learning curve with
ruby is /less steep/ but i will be doing things /faster... in a shorter
space of time/ ?
