and yes
or in other words give the user the ability to specify when he wants the
fallback to global and not doing a fallback to global per default. That way
we get an efficient lookup witout a double retry:
1) local
2) autoload
3) fail
while the user can stack above in first:
1) local
2.1) autoload as above == global
2.n) autoload
3) fail
and also stack at the end:
1) local
2.n) autoload
2.X) autoload as above == global
3) fail
Best regards,
Marcus
