fixes #196

The code that will be compiled by the JitCompiler will almost certainly need access to the modules in order to perform said compilation.

invokeExact is more performant, and should be used wherever possible rather than plain invoke.

Bindings in slinc needs to be minimized to hopefully write code that mirrors what a human would write.

This is less safe than storing the Readers/Writers in the ReadWriteModule due to the possibility of mixing runtimes/modules, but we don't have a well-engineered solution to that at present anyway....
