It was thus said that the Great Rena once stated:

Well, the fourth one can also be written [1]:
syslog('error',"warning: x=%d",d)
Now, as to the difference between:
syslog('error',"warning: x=%d",d)
and
syslog.error("warning: x=%d",d)
is a matter of taste. I prefer the former, as it's actually less code (one
function vs. eight). The later seems popular with the OO crowd (in my
opinion).
