If so, then we haven't gained anything, and the only thing that would
satisfy such people would be for every function name and operator to be
unique -- something which is impossible in practice, even if it were
desirable.
Well... We could maybe borrow from REXX... and use ||
for
concatenation.
Of course, REXX has the minor idiosyncrasy that everything is a
string unless the context needs a numeric...

How about "~", which is currently has only a unary form:
>>> "foo" ~ "bar"
'foobar'
>>> [1, 2, 3] ~ [4, 5, 6]
[1, 2, 3, 4, 5, 6]
Think of it as meaning "followed by".
Actually, I wonder if it could also be used with generators to mean
itertools.chain:
>>> r1 = range(3)
>>> r2 = range(3, 6)
>>> for x in r1 ~ r2:
print(x)
0
1
