Comment #4 on issue 2185 by [email protected]: subs issues http://code.google.com/p/sympy/issues/detail?id=2185
Whether you enforce integer power subs for commutatives is another issue. You (apparently) should definitely not be doing algebraic (non-integer) subs for noncommutatives, so I just added that check to the _eval_subs routine so non-tinteger subs are not allowed when the base is noncommutative. In other words, one shouldn't have to give a hint to get the right behavior if non-commutatives are involved. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
