lot of work

got myself in a lot of work because i'm not respecting
interfaces.. maybe fix that temporarily? it was necessary for the
control structures because they're low-level, but maybe not for the
rest of the code?

next: the 'compositions' macro parameterized by:

* source name space
* target name space
* compilation macro

maybe it's best to take a step back, and respect the interfaces.. it
looks like this is going to work, so i can just as well make the step
and replace the entire vm code.
