[Expectperl-discuss] eof treated too specially :)

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

  If I try to

$exp->expect($t, ["password"]);

it works just fine, but if I try to

$exp->expect($t, ['eof']);

I have problems because it wants me to supply a coderef to call.  So I get
an error message which says "Can't use string ("") as a subroutine ref while
"strict refs" in use at /usr/local/perl561/lib/site_perl/5.6.1/Expect.pm
line 829."  I have to

$exp->expect($t, ['eof' => sub { }]);


  In a related issue, it seems you have to use the arrayref syntax to get
the special eof treatment.  You can't

$exp->expect($t, 'eof')

or you'll be matching the literal string 'eof.'


  It's too bad we can't create a special magical regex+ object that could
stand for a regular expression or a literal string or a special condition
like eof.  I'm sure that would greatly simplify the Expect.pm code. :)
Hmmm... this gives me something else to lie awake thinking about at night.

  BTW, I think expecting eof is going to shape up to be an answer to some
FAQs in the future.  If you're interested, all of this originated in a use
Perl; thread at http://use.perl.org/~djberg96/journal/5430 .
