This isn't something that is usually done with zkl as the compiler is fast enough (for scripts) to just run the source and let it get compiled and run. But, it can be done. Note: The binary still "links" against zkl (the VM) so the #! is required.
Since the #! parsing is done by a compiler front end and was designed to be used from the command line, we'll do that by forking zkl to compile the source if it is newer than the binary.

// compiled file doesn't exist), compile up a new version
