I expected less, given that the generated code does mostly what the
compiled byte interpreter does, saving only on the time taken to loop
through the byte code.

I only wondered why the TODO entry favoured CCL, as it was simpler to
try the byte code first. The changes to function calling required for
the compiled byte code would count towards a similar effort for CCL.
