[ shrug ... ]  It's right: _t1 is not a scalar variable.  (It has
the composite type s.)

The reason this is problematic is that writing a composite variable as
the target of a FOR IN SELECT loop is defined as assigning all the
columns from the SELECT into fields of the composite variable.  Which
is not what you wanted to have happen there, even if we were to extend
the definition to allow a mixture of scalar and composite variables in
the target list.

I'd suggest declaring a record variable and using that as the target.
