Undocumented Autonum Feature? (I hope)

[Jenna Klein]

While the autonum command is simple enough, is there a way, perhaps 
undocumented, to create the autonumbering as part of a create table 
command? I know other SQL variants allow this (I'm thinking of MySQL in 
particular)

Something like: CREATE TABLE WithID (MyTableID INT NOT NULL PRIMARY KEY 
AUTONUM(1,1))

If there isn't already such a feature, would it be trouble to add it?

Thanks!
