New comment on block [block-idp7718512]

bad wrapping for the comment results in an error when you try to paste this into utop. Breaking the comment onto two lines will fix that.

Context:

The structure of the code is pretty straightforward --- we're just pattern-matching over the structure of the data, doing the appropriate calculation based on which tag we see. To use this evaluator on a concrete example, we just need to write the base_eval function which is capable of evaluating a base predicate.

That was a bug in utop. Now fixed. If you update to the latest version in opam, everything should be OK.
