[Expectperl-discuss] Cool feature: logging subroutine

[Blackstone, J. D. <jda...@ci...>]

  I haven't read the FAQ in ages.  I decided to look through it again today
and found this neat feature, which may have been there forever:

  You can log all your output to a file, as in $x->log_file($filename), but
to be even more flexible, you can specify a subroutine reference to receive
the output, as in $x->log_file(\&subroutine) .

  I get the feeling that this can be abused in many useful ways. :)
