Hmm... I'll answer my best and you please tell me if that answers the question. First, context is accessed as context() property, in get-style:  my ( $a, $b, $c) = context and in set-style:  context $a, $b, $c.

When one is concerned only with calling predicate functions, such as tail() or read(), context is usually only set, and is not read. It's not impossible, just unneeded.

However, when one needs to write a custom function, that is on the receiving end of context, then the function needs to read the data passed through context. For example, you need to write a wrapper over IO::Lambda::sleep() that also prints number of seconds to sleep: 

sub my_sleep(&)
{
   print "sleeping ", context, "seconds\n";
   &sleep(shift);
}

And that is about it. If the caller wants to restart the call by 
context 5;
my_sleep { again if $again }

[download]
then the framework makes sure that 5 is still stored in the context, as my_sleep is called from within again().

Does that answers the question?
