leftw, rightw
Synopsis:
$leftw(<count> <word list>)
$rightw(
Technical:
These functions are used to return a slice of the input list, from either the
beginning or end of the list. It returns the indicated number of words from
the beginning or the end of the list.
Practical:
This is mostly useful when you know you always want to get a certain number
of starting or ending words in a list, regardless of what they are. They are
analogous to $left() and $right(), except they operate on whole
words instead of characters.
Returns:
list of words from beginning or end of word list
Examples:
$leftw(2 hello there how are you?) returns "hello there"
$leftw(-1 hello there bob) returns nothing
$leftw(7 hello
there bob) returns "hello there bob"
$rightw(2 hello there how are you?) returns "are you?"
