This has been discussed before and not gone anywhere, e.g. [1] [2].
I think there have been more threads but that was all I found in a
quick archive search. Anyway, as those threads illustrate, there is a
lot of room for variation in how you spell it, where you can write it,
and so on. My own inclination is to not do anything here until/unless
the SQL committee standardizes something, because there's too much
risk of finding ourselves incompatible with the standard.
