Synopsis:
$word(<index> <list>)
$notw(<index> <list>)
Technical:
The $word() function returns the single word in the given list that has
the given index in the list, counting from 0 (zero). Its counterpart,
$notw(), does exactly the opposite, returning the entire string, minus
the indexed word (again counting from 0).
Practical:
These functions are useful when you need to get (or hide) whatever word
is in a particular position in a string of words. It's mostly useful
when you know that you always (or never) want the Xth word in the list,
regardless of what it is.
Returns:
word: indexed word
notw: string without indexed word
Examples:
$word(2 foo bar blah) returns "blah"
$word(4 foo bar blah) returns nothing
$word(-1 foo bar blah) returns nothing
$notw(2 foo bar blah) returns "foo bar"
$notw(4 foo bar blah) returns "foo bar blah"
$notw(-1 foo bar blah) returns "foo bar blah"
