$rest(<text>)
$rest(<num> <text>)

• If the <num> argument is not provided, 1 is the default value.
• The return value is <text> with the first <num>th characters removed.
• If you think that the first word in <text> may be a number, better to be safe than sorry; specify an explicit “1” for <num>.

This can be used to remove the initial character of a string, or to remove multiple initial characters from a string.

<text> with the first <num> characters removed.
