Fwd: Re: [Python-3000] Removing functions from the operator module
[Collin Winter]
I don't suppose you've changed your mind about removing operator.truth and operator.abs in the seven months since this discussion?
[GvR]
No, though I think that operator.truth should be renamed to operator.bool.
I like the idea that for each built-in op there's a callable in operator.
It makes sense to me that built-in ops like + have a corresponding operator function like operator.__add__(), but I don't follow how this logic applies to abs() and bool(). ISTM, operator.bool and operator.abs would not add any value beyond what is already provided by __builtin__.bool and __builtin__.abs. Raymond

FWIW, I've always thought of the operator module as a place to look when I need to pass some bit of syntax (eg., attribute lookup, "in", addition) to a higher-order function. bool() and abs() aren't syntax, so I would never look in operator. Collin Winter

abs() is not syntax but bool() is part of every syntactic construction that takes a truth value argument (if, while, and, ...) A bientot, Armin
