Access Violation exception

[lampersky]

@sebastienros is there any cycle detection mechanism in parlot?

example code which will break your app:

var loop = Deferred<string>();

loop.Parser = loop;

var test = loop.Parse("hello parlot");

or

var loop = Recursive<string>(c => c);

var test = loop.Parse("hello parlot");

I would expect this will detect infinite loop and return null instead of crashing.

We could do something similar to what we did in Fluid
