This interpreter operates directly on the source language, and implements it faithfully without regard to any specific implementation technique. This does cause some problems - I am quite confident there are exotic problems related to interactions between size annotations and empty arrays, that are handled differently by the compiler and interpreter. This interpreter is *very* slow. It is not suitable for running programs on all but the smallest data sets. It may be possible to speed it up in the future. On the upside, it supports a very nice interactive environment that supports the full language, including modules. It completely replaces (and removes) the old core language interpreter. Closes #537.

There is dubious value in having it work on the core language.
