I like the idea of making concatenation more pretty, quite frankly.
No one has really responded to Pavel's contention that this is what
to_char() is for. Twice the code paths = twice the bugs, twice the
places that have to be updated when some new feature is added, etc.
On the other hand I don't really strongly object if someone else wants
to do the work, either. I do think allowing for upward compatibility
with future extensions is probably smart, regardless of how simple or
complex the first version is.
