Yes, it was… (I need to get some sleep).
Yup, that would be amazing. I’m not sure how far ElixirScript is right now with supporting processes; there were some caveats earlier if I remember correctly, but yes, I am sold on this idea 
.
As for the native GUI idea: I’m now working on a semi-direct (and thus stateful) wrapper to :wx_widgets called Wex (which is far from finished, because :wx_widgets is HUGE, and there are some design choices that still need to be made). Another to-be-written library that has the WIP-name Candlelight will wrap Wex with its own structs that are stateless representations of a certain GUI. Candlelight will use MapDiff to check for changes in theis GUI representation, and run the required Wex functions to update the changes.
To the end user, this means that a GUI can be constructed and altered by nesting the Candlelight structs (or functions/macros(?) that create them) in a very simple and clear manner.
Very similar to how Elm allows the creation of HTML content using its HTML DSL. However, GUI elements in WxWidgets are a lot more complicated than a HTML representation (which is just ‘text’; we let the browser figure out how it should look) so there is a lot of work to be done 
.
