IIRC, pg found himself against it too, but rtm was for it.

One feature I like in PHP is the use of the dot (.) for concatenation. We've already loaded up that character quite a bit here in Arc, with its use in conses, rest parameters and for the ssyntax `a.b` => `(a b)`. But concatentation is at least vaguely isomorphic to consing. I wonder...

Probably not. `+` is your best bet, IMHO.

I should mention, just for completeness, that haskell uses ++.

Didn't know that. Could you give a quick example?

In haskell you can designate any sequence of characters as an infix operator. Here's the definition of ++ from the prelude (http://www.haskell.org/onlinereport/standard-prelude.html):

  (++) :: [a] -> [a] -> [a]
  []     ++ ys = ys
  (x:xs) ++ ys = x : (xs ++ ys)
so [1, 2, 3] ++ [4, 5] = [1, 2, 3, 4, 5]
