Compilation to executable probably provides roughly the same
performance as not compiling.  It's possible that file i/o or file
layout will change this slightly, but no interesting optimization
happens in the "compile to executable" process.  It's mostly just a
packaging step -- useful when someone like your professor wants an
executable file.

The executable will embed the results of byte-code compilation.

Add an explicit `require` of the missing dependency in your main file
(the one that you're compiling to an executable), like this:

    (require math/private/array/typed-array-indexing)
