CPS::Future - compatibility wrapper around Future


This module provides a compatibility wrapper around Future. The code it used to contain was renamed to move it out of the CPS distribution. Existing code that refers to CPS::Future should be changed to use Future instead.

$future->( @result )

This subclass overloads the calling operator, so simply invoking the future object itself as if it were a CODE reference is equivalent to calling the 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 CODE references. See the done_cb method instead. This overload behaviour will be removed in a later version.
