[gclist] Prior work?

[Daniel Wang]

Thanks, for all the feeback. For this particular application the specialized
scan function is there for type safety reasons, improved performance isn't
the actual goal. I just noticed a small benchmark with an explicit scan
function beating the obvious C version, and was wondering if for more
realistic systems building an explicit scan function is going to be a
performance win or not. I guess, I'll just have to run an experiment on a
large system to see what happens.
