Jens Alfke asks:
>Maybe pass the column name as a string, i.e. `attr('H',3)`
2 problems with that idea. First, the first argument has to refer to a value in the virtual table in order to invoke the overridden version (overrides are per table, so I use the ppArg to bind function invocation to associated virtual table). Second, if I created a view that gives column H a name of Total, I’d want to the function call to be attr(Total,3). I don’t know how to make the function figure out that attr(‘Total’,3) really means column H in some table.
