Well, that's an "engine" one would need to create complete support for.
Some things would be nicer to specify via C++ templates rather than
function hooks.  C macros can sort-of be used for providing similar
functionality, but they are quite more opaque to compiler, debugger, and
programmer and more ad-hoc.

Not proposing to move to C++: that would seriously impact the ability to
integrate into other systems.  Just a musing.
