The following should work:
{{{
sage: from sage.monoids.automatic_semigroup import AutomaticSemigroup
sage: R = IntegerModRing(101)
sage: M = AutomaticSemigroup(Family({1: R(3), 2: R(5)}), one=R.one())
sage: sage: sage: e = M.from_reduced_word([1, 1, 1, 2, 2, 2])
sage: e.reduced_word()

AttributeError Traceback (most recent call

[...]
AttributeError: 'AutomaticMonoid_with_category.element_class' object has
no attribute 'construct'
}}}
I'm uploading a fix.
