[REBOL] Re: Extend system functions

Hi Alessandro,
<< Does anybody know how I can "extend" a system Rebol command? >>
You can replace any system command you want, unless they're protected with
the PROTECT function, *however* changing the behavior of standard system
functions is generally frowned upon because it just gets too confusing. The
recommended approach is to create your own functions, with a similar name.
As far as extending their functionality, try using the SOURCE function. Many
routines are written in REBOL (they are called mezzanine functions) and you
can see the source code to them so you can copy it right out and extend it.
