In practice, I may need to compromise on at least one of those. If I resort to a compromise, then I would benefit from being able to absolutely trivially have different executables of the same source code which differ in their mathematical implementations (such as one executable using fixed-point numbers and another executable exploiting fractions to represent real numbers etc.). I can already substitute one reification of an abstract datatype by another, but I want this without any overhead.
