New description:
Other implementations of is_integral_domain allow an argument 'proof'
whose default value is False. Infinite polynomial ring omits this
argument in its definition of is_integral_domain:
{{{
sage: W = PolynomialRing(InfinitePolynomialRing(QQ,'a'),2,'x,y')
sage: W.is_integral_domain()
-------------------------------------------------------------
TypeError Traceback (most recent call
last)
...
TypeError: is_integral_domain() takes exactly 1 argument (2 given)
sage: W = PowerSeriesRing(InfinitePolynomialRing(QQ,'a'),'x')
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
...
TypeError: is_field() got an unexpected keyword argument 'proof'
}}}
