Subject: [MOO-coders] index() for LIST

Is there an analog built-in command or available verb that would do
similar thing as index() for a STRING but for LIST. That is, it would
allow one not to use a for/endfor loop and a if/endif to check if one guy
is present in there (if it could also return its position, oh! it would
be heaven...;)
Thank you;)
rv,

Why yes.  It's called in.  But its not quite a verb, its a keyword.  The
syntax is:  thing in list
and it returns the index of the thing in the list, or 0 if its not
found.  As an example, do this on a MOO where you have a progbit:
;1 in {0, 1, 2, 3}
