repr error in printing 3+ arg forms of :comparison operators

[vtjnash]

for example:

julia> :(in(1,2,3))
:(1 in 2 in 3)

while that output expression would actually be interpreted as:
Expr(:comparison, 1, :in, 2, :in, 3) and lowered to (1 in 2) && (2 in 3)

How should it be represented then? I think the prefix notation fits since the infix notation makes no sense as you said.

in prefix notation. the infix notation shouldn't be used since it doesn't round-trip correctly
