[Expectperl-discuss] RE: Calling expect without a timeout parameter

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

  I just answered my own question by watching the debugging information.
Calls to expect with only one parameter will treat that parameter (a string)
like the timeout (thank you, Perl; in five years that's the only time I ever
regretted the ability to mix and match numbers and strings with impunity)
and expect nothing.

  So I've just been getting REALLY, REALLY, LUCKY. :)
