4.3.2 MONOLITHIC INTERFACES AND NONCOMPOSITIONALITY

The main problem with current code generation approaches is that they treat blocks in a monolithic

way, meaning that they assume that all blocks must conform to the same interface. In the case of

the example in Figure 4.3, the specific problem is that all the blocks are assumed to have a single

output function that accepts all inputs and returns all outputs. A single output function is enough

when every output depends on every input, but it is not rich enough to express more complex input–

output dependencies. In particular, it is not able ...
