        32k? Luxury! In my day we had 128 bytes on a RAM/IO controller chip and we liked it!

        128 bytes?? In my day we had "high", "low" or "PWM", and if you accidentally put "PWM" into the "high" wire magic smoke came out

        .@paul_snively So if we try to project into the future, and I claim that in 20yrs we'll all have "phones" with 16TB RAM, could we guess why?

        with 16TB I might have enough to add a high-score table to my side-scrolling shooter

        So did reordering subroutines by call frequency improve performance?

        By the way, I also started with BASIC. It's what got me hooked...

        .@paul_snively The irony is, a very similar trick of reordering implicits still works for improving Scala compile performance...

        If you give each implicit a unique priority in a stacked trait seq, compiler doesn't need to check ambiguities.
