"Efficient" doesn't offer a lot of benefit at this point in the program. The
difference is fractions of a microsecond. "Readable" will help you more in
the long term.
My personal rule of thumb says that exiting belongs in the main application.
Ending the application is not integral to the actions "foo" or "bar". I
assume that from the description - you don't care which subroutine runs, the
program should exit after any of them. So I would exit from the main
program. Maybe something like this...
If ($foo){
my_sub_foo();
# Is the program going to continue from here once sub foo has ended and
I have not called exit here or in the sub?
}
elsif ($bar){
my_sub_bar();
}
else {
my_other_sub();
}
exit 0;
