See the discussion in #609 for a test case.

It does fix this error.

Since I haven't used this macro before, reading the documentation, if there is a single variable, there seems to supposed to be an error, but Is the example about supposed to be skipped as an assignment since there isn't a single variable on the left?

The parser::Assignment::Formula new method is called for the entire string in the example, and the type of that string is not an Assignment. It is resolved to a Number by the Value::Formula package. As such it does not have the data hash key which an Assignment would have. That causes an error on the later lines of the new method. Basically, not everything that is passed through the new method should end up being an Assignment.

@dpvc can hopefully give a better explanation, and I am hoping he can take a look at this when he gets a chance.

Just a heads up, should this also be added to develop? Or is the plan to pull in any hot fixes to main back to develop at some point?

[drgrice1]

Yes, this will also be added to develop once it is approved. At this point all hotfix pull requests that have been merged have also had a duplicate pull request merged into develop.

[dpvc]

This looks reasonable.
