In this particular case yes, but there is one more important
difference. In the first case the new() subroutine is looked up first
in the BOA::Logger2 package, then in the "parent" package (specified
via @BOA::Logger2::ISA or "use base ...."), its parent package etc.
It's a method so the inheritance rules apply.
In the second it's only looked up in the BOA::Logger2 package and if
not found there perl emits an error message.
