The recent evolution of Sage seems to break the print(eval(read))
equivalence :
sage: var("a0, a1") (a0, a1) sage: "%s"%a0^a1 'a0^a1'
So far so good. But :
sage: eval("%s"%a0^a1)
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last) Cell In[54], line 1 ----> 1

exponentiation, not '^', which means xor\n" 953 "in Python, and has the

which means xor in Python, and has the wrong precedence.
But, inconsistently :
sage: "%s"%a0**a1 'a0^a1'
In other words, Sage insists for reading x**y and for printing x^y.
Unless I’m missing something, *these choices are inconsistent*.
Should I file an issue ?
