Puritas, from Latin, means linguistic correctness, from a lexical point of view.

In this talk, you will be exploring and walking down the bumpy road of trying to bring side-effect free code to F#. The journey started, in Ramon's case, a few years ago while working for an IT consultancy company where Ramon made: Delegate.Sandbox, a library providing a Computation Expression named SandboxBuilder, sandbox { return 42 }, which ensures that values returned from the computation are I/O side-effects safe. The library is built-on top of .NETs Partially Trusted Code Sandboxes. The path of exploration somehow stalled.

Now with new ideas under the hood and great tooling provided by Microsoft and the amazing F# Community, the journey continues towards bringing this missed feature to an already brilliant and loved programming language, that is used by thousands in the magnitude of 4.

Hopefully one day, the reserved keyword: "pure" (The Holy Grail of F# keywords) will be claimed, and we will be able to use it with ease as we do with other keywords such as: seq, async, query, lazy and so on.
