[Expectperl-discuss] Calling expect without a timeout parameter

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

  Looking through some old source code (wow; when did it get to the point
that I had "old" code written with Expect.pm?), I discovered some routines
where I had written things like:

$x->expect("String");
$x->send("a\r");
$x->expect("String2");

  Apparently I got confused and was thinking of TCL/Expect's expect command,
which does not take the timeout as a parameter.

  Strangely, this code seems to work.  Is the expect() method designed to
work like this, or am I just getting lucky by cramming the right things into
the buffer in the right order and not running into race conditions?

  I'll probably digging through the source code to answer this unless
someone knows off the top of their head.  If this is a feature, not dumb
luck, it could go into the docs somewhere.  (And if it's in the docs, I'll
accept a cluestick to my skull.)

  Thanks.
