=head1 NAME
C<CPS::Future> - compatibility wrapper around L<Future>
=head1 DESCRIPTION
This module provides a compatibility wrapper around L<Future>. The code it
used to contain was renamed to move it out of the C<CPS> distribution.
Existing code that refers to C<CPS::Future> should be changed to use C<Future>
instead.
=cut
=head2 $future->( @result )
This subclass overloads the calling operator, so simply invoking the future
object itself as if it were a C<CODE> reference is equivalent to calling the
C<done> method. This makes it simple to pass as a callback function to other
code.
It turns out however, that this behaviour is too subtle and can lead to bugs
when futures are accidentally used as plain C<CODE> references. See the
C<done_cb> method instead. This overload behaviour will be removed in a later
version.
