> the reason why coding is so difficult is that interfaces are often too darn complicated to keep track of?

Haven't brought this up in a while. Ya. I feel coding is hard due to complex interfaces. I once worked on a programming abstraction, mechanisms, aiming for a consistent interface for easy composition.

Key features of mechanisms were:

1) All data types were mechanisms

2) A Mechanism needed no context (parameters) when invoked.

3) Composition of a mechanism could take any number of mechanisms (primitives at this point are treated as mechanisms) and return a mechanism.

4) Upon invocation, a mechanism functions in one or more modes, returning either a primitive data type or another mechanism.

Think of it as currying or Lisp's S-expressions, but supercharged, envisioned as a base for Visual Programming Languages.

An example of composition using mechansisms:

// Compose

addTwo = print( map( add( 2, emitFromRange(0, 20, 4) ) ) );

Which is saying "Print a mapping of adding 2 to an emitted range from 0 to 20 by 4."

// Invoke

addTwo()
