Thanks for the link, Spencer. This obviously belongs in the FAQ for now.

I was interested to define ++ as operator for concatenating strings. I
can define + for this purpose, but for ++ I get
julia function ++(x::String, y::String)
x * y
end
ERROR: syntax: expected ( in function definition
I looked up // in Rational.jl, but did not
It is not, look at julia-parser.scm for the list of operators you are able
to define.

I think the issue is that ++ is not an operator in julia.

And I thought Julia allows to define operators as users like.
Is there a special reason (inconsistency) why ++ would not not be allowed
while // is?
Could this be changed by an appropriate entry in
Julia does not allow user-defined operators. There are just a lot of
pre-defined operators. We could add ++ as an operator, but we'd have to
decide how it parses and what it's precedence is. In Haskell it's an infix
operator used for concatenation. In C it's a prefix and postfix operator
that
