Comment(by SimonKing):
Snap diagnose: #11316 changed when the term order is created, and I
changed the order of things as well. In consequence, variable names are
assigned twice, which yields an error. Example:
{{{
sage: from polybori import *
sage: declare_ring([Block('x',2),Block('y',3)],globals())
Traceback (most recent call last)
...
ValueError: variable names cannot be changed after object creation.
}}}
