Meanwhile, the foundation laid by Alan Turing, and also applicable to Church's Lambda Calculus (stated earlier), was worked upon by Church's student and American logician, John Barkley Rosser.
That set of mathematical rules is optimized to help people describe complex distributed systems comprised of multiple processes executing in parallel--unlike lambda calculus.
A good intuition for the semantics is to imagine two copies of the simply typed lambda calculus augmented with a new type t.
Some topics would benefit from a bit more follow-up, and others--like the lambda calculus and the contravariant basis--could easily be omitted.

The authors start by describing how functions can really depend upon their arguments and how close this notion is to functions which art, typed by propositional relevance logic much like the Howard-Curry correspondence between intuitionistic logic and the lambda calculus. Within the computer science community, this comes out as Scott's notion of "strictness".
This approach, which we will further develop, is by itself of high interest to the rewriting community, but our work will also be relevant to the typed lambda calculus and programming languages communities.
The new C++14 standard allows lambda calculus as we demonstrate in the applicative section of implementing conditionals, booleans and numbers.

The common framework considered here is a hierarchy of intermediate languages, all of which are subsets of the lambda calculus. Our description of an implementation consists of a series of transformations [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], each one compiling a particular task by mapping an expression from one intermediate language into another.
