    The fast path (used by elc) parses the data straight from the file,
    whereas the slow path loads the file into a buffer (which includes any
    decoding if needed) and only then passes the resulting byte-stream to
    the parser.

If the coding system were known in advance to be utf-8, it would
still need to be read into a buffer, decoded, and parsed from there.

You can see how fast this would be by putting a coding tag
on the file.  How fast is it, compared with reading source
without the coding tag?  How fast is it, compared with reading the compiled
