 ## `DexModule` run a whole bunch of Dex code defining a module.
 Similar to `evaluate`, `DexModule` takes a string full of Dex code and runs it.
 However, DexModule is a bit more powerful.

 The function type it defines is a `NativeFunction` as described above.
 In functionality, `dex_func` is very similar to `NativeFunction ∘ evaluate` except that it does a whole ton of the work at parse time -- including compiling the Dex function.
