Not by me. :-)
The biggest argument about the money type is that it has an unrealistic
limit. With this change we can go to almost one hundred thousand
trillion dollars. That should handle even the US federal budget for a
few more years.
The benefit of the money type is speed. Because internal operations
are done on integers they can generally be handled by single CPU ops.
My tests on the 64 bit version show 10% to 25% improvement over numeric
for many operations.
