TODO:

flag for allocation testing:
- before each test, push an allocator specific to the test
- allow a postamble that inspects / expects a certain number of allocations to have been made
Spike: resolving multiple references to the same dependency
- ie. two files which both #load the same file
- Reason: If we can resolve this, it would enable compiling tests as a single compilation unit rather than multiple, which will significantly speed up test compilation
