Builtin common functions
========================
Functions that are used by nearly every program, and very frequently,
could possibly be built-ins.
An example is logging:
func var SomeType.do_stuff(int i)
{
debug "Starting. \={i}"
if i < 0 {
error "i may not be negative. \={i}"
return
}
debug "Done"
success # code paths that go here may not have called "error"
}
In this case, the "debug" calls would get wrapped by guard conditions
(or possibly even compiled out).
Should logging be allowed in functions that don't take any arena parameter?
- If not, how should the log configuration be controlled?
(and where should log output go?)
- Perhaps there could be a special case for debug logging?
