I find myself in need of something along the lines of Python's
`re.split` and `re.findall` all the time. E.g. splitting an ip into an
array of octets.

FWIW, ksh has two redirect operators that can be used together with
`read` to get something like this. They're somewhat difficult to use
IMO:

        <#pattern     Seeks forward to the beginning of the next line
containing pattern.

        <##pattern    The same as <# except that the portion of the
file that is skipped is copied to standard output.
