Functional can be tricky to debug, as the frowned-on "intermediate state" of imperative programming makes for great x-ray examination points during debugging.

Functional can be tricky to debug, as the frowned-on "intermediate state" of imperative programming makes for great x-ray examination points during debugging. The backlash against OOP is partly because existing OOP engines are limiting in many languages. Passing, grouping, and custom-scoping of "blocks of code" (BOC) should be more flexible so that we are not forced into hierarchies or spaghetti scoping. We need new languages that make managing and scoping BOC more flexible. I want to define the scope, not let Nadella or Bezos do it. The distinction between a lambda and method would then be fuzzier. BOC's would no longer be forced to be one or the other. (One these days I may make a proof-of-concept language.)
