Which was added because most if not all other precompilers allow this syntax
and of course it didn't do any harm until now.

Couldn't agree more.

I'd like to figure out exactly what syntax other DBMSes accept. It appears
Informix allows the cursor name as a variable but has neither FORWARD/BACKWARD
nor FROM/IN. Zoltan, could you please check whether my docs are right? 

A quick google search seems to suggest that the same holds for Oracle that
apparently allows less options.
