Stackable Functor Allocation

Is a refactoring pattern. It aims to keep the Functor operator() allocation free and the Functor body free of references. The strict memory is adressed entirely as a stack, as heap (size known at compile time), but not as free-store.

test_SFA

The refactoring pattern.

test_MOLE

A related GPU refactoring pattern for invertible functions. Here, the memory requirements are relaxed. Not in the original sense of stack.

test_INV

Defunct.
