The bound() function comes from our decision on the SOURCE issue


(I suppose I could elaborate the issue description...)

The useMentionOp issue is also relevant

Discussion of evaluation order has come up up during our

All these issues are closed.

I don't recall any discussion of the bound() test interacting
with order, but perhaps this is the thread you're thinking of?

"If "OR" only evaluates the RHS is the LHS is false (programming
language style) 
we are back in order dependent territory."
