Modules as views on this database of functions is genius.

Most of the problems that Joe talks about with modules go away if modules become just a mutable collection of functions, and functions can be in more than one module.

Only if the relationship between functions needs to be a directed graph. If a strict tree with no cross connections is sufficient, then there should be no reason for two classical modules to share identical functions. The existence of such a function would suggest instead the need for a third module.

Considering the idea of functions that need a directed graph to describe their relationships makes it pretty obvious, at least to me, that it's a bad idea.
