[FullyFunctional]

There's really not much new here. All these ideas have been used in other languages previously, but perhaps not in exactly this cocktail.

I'm decidedly in the not convinced camp.

[imtringued]

I am not convinced because far more pressing aspects have been ignored. One million programmers means program structure is more important than the syntax used to write the algorithms.

Does the language address common pain points like modifying data structures? Does it make it easy to extend existing code even without having the ability to change it?
