It's inspired by a similar tool called `pyp`, which I considered extending but ended up going my own route instead. Here's some more information on why: <a href="http://gfxmonk.net/2012/03/28/why-piep.html" rel="nofollow">http://gfxmonk.net/2012/03/28/why-piep.html</a>
Why not just bite the bullet and add optional {}:s to Python instead, so you don't have to learn a tool just to get normal command line (/oneliner) usability?<p>The total sum of complexity to learn/use would be about the same (and Python would get multi instruction anon funs.)
