:Just as another data point, it would be interesting to see the overhead

:The alpha versions of these operations are already non-inline since it

Well, you can change those inline's to real functions and run the
program. But I'll tell you what you will see... procedure calls
are very cheap on intel cpu's, so it will probably have an effect
similar to the global assignments I added in the second half of the
test.
