You weren't that wordy about it at the time; you simply said your first impulse was to "blame GNU bash". That's a bit of a sore point -- BASH, as a shell many new users start with, has a low value in some admin's eyes -- the habit of new users calling all shell scripting "bash scripts" doesn't help -- and seems to get blamed for everything from their own bugs to poor weather as a result. Even though it's just doing what a Bourne shell does. Blame him if you must. Smilie

In my opinion, the ksh approach makes life a little easier.
Perhaps, but it's not something that can really be changed now. Bourne is what it is, and changing the ordering would change what happens in a lot of scripts because it cuts both ways -- suddenly scripts could be setting variables in the main shell they never did before...

I bet BASH'll add it as one of it's many fiddly setopt options someday.
