Overloading boolean operators sounds like a bad idea. That's what & and | are for.

But it would be awesome if you could just overload a < b < c. But I guess there's no reasonable way to do this without really changing the language semantics. Perhaps if there were a straightforward way to tell and and or to not short-circuit.

Wouldn't it be very hard to disambiguate slice notation from dictionary creation?

For example, is the following a set of slices or a dictionary?

{1:3, 3:4}

I have no opinion on the additional operators, but will take your word for it (and I have no objection). Overloadable boolean operators I would have found useful on occasion.

You mean Unicode identifiers :)

I would rather create a custom import mechanism that converts operator-enhanced Python (or whatever) to plain Python before importing a module. There would be drawbacks (e.g. inability to use custom operators directly in the standard Python interpreter unless a custome shell is created) and I am not sure whether this is yet/soon-will-be possible (I believe Brett Canon would be the one to ask about this).

Thanks for the reminder about this idea. I thought it was clever when I first saw it proposed.

With Python 3's allowing of unicode literals, you might even convince me that using something like this with a special unicode literal (i.e. that looks like a dot) would be acceptable.

Hmm... Now, we just need someone to propose an appropriate Unicode character to make a variable out of...

ISTR discussing a module in c.l.py that produced a CustomOperator class overloading the __ror__ and __or__ operators; given this (and the necessary “magic” inside the code), you could:

from custom_operator import matmult

a= b |matmult| c

matpow being an instance of CustomOperator.

If one overloads other special methods as well closer to the real meaning of the custom operator, it's possible to take advantage of operator precedence:

from custom_operator import matmult, matpow

a= b *matmult* c ^matpow^ d

A hack, I know :)
