deferpy

Deferred function calls are pushed onto a stack. When a function returns, its deferred calls are executed in last-in-first-out order.

The Go Blog has a good explanation of the behavior of defer. This package attempts to recreate the behavior as closely as possible.

Installation

 $ pip install deferpy
