I noticed that the following grammar

a = "constructor"

fails in version 4.0.2 with

error parsing grammar
Cannot read properties of undefined (reading 'length')

This was not the case in version 3.0.2

Validated, and I see where the problem is. Investigating solutions.

I'll do a release later today, after fixing #513 and #522.
