A small remark for Todd's proposal: I think you should treat the new not (bNOT
in the original proposal) differently: it's not binary, so it should not have 2
dunders, the right one is not needed (or there is only the right one, in a way,
but other unary ops use the classic dunder iirc...)

Oh, I see, I thought he wanted to override the original logical operators.
I don't like adding more operators just to make symbolic equation
generation simpler. I think keeping the language simple and using the
"numpy.logical_and" function is better than making the language more
complicated for a

Todd is not proposing to add dunder methods for the existing "or" and
By the way, these are not "partial functions", and shouldn't be called
that. These are "partial function applications".

This doesn't work because the logical Boolean operators short circuit in
Python. So you could not even define these operators for the regular
Python types. Your two examples numpy and SQLAlchemy don't want this
short-circuiting behavior, so you would never want to write anything like

just like set() -- which I think has been mentioned here already.
