I see a meachanism like
new_syscall(str, args) = syscall(hash(str), args)
where hash() is chosen to guarantee unicity (that wouldn't be hard to find).
we then have both performance (working with indexes instead of comparing
strings) like what is currently available, and the flexibility of strings.
Note that this goes in the same dynamic "wind" than loadable modules and
the like: static gets old...
cheers,
