Looks good. Thanks. Should we add a small test to tests/test_exprParserYacc.py?

There's already coverage for this syntax in there: https://github.com/lsst/daf_butler/blob/tickets/DM-45933/tests/test_exprParserYacc.py#L165

Ok. I wasn't sure if that part of the code testing for POINT syntax was also responsible for checking for the negative value.

As far as the grammar is concerned, POINT() is an arbitrary function and its parameters can be any expressions.
