I failed to look closely at your example before.  Apparently you are
thinking of the syntax as being <parameter name> AS <expression>.
I was thinking of <expression> AS <parameter name>, which seems to
me more parallel with the SELECT-list syntax for labeling columns.
I am not sure offhand if one is harder than the other to implement.
