Many of these are just special cases of N-operand operators. The
challenge is an operator syntax that allows an arbitrary number of
operands (and which doesn't look like a single operand which happens
to be a list, although that is another way of doing it).
Yes, I have trouble thinking up any naturally ternary operations. As
soon as the notation has brackets and a comma in it, it is natural to
extend the number of operands arbitrarily. We do zero, one, two, many.

Think again: function call is an N-ary operator

all the unary, binary, ternary operator can be thought a syntax sugar
for calling functions (some gotcha: laziness).

btw, is there any language that have zero-ary operator? otherise we
should go one, two, many not zero, one, two, many...
