If it is important that the maintainer notice that each choice is mutually exclusive, then make them extremely obviously mutually exclusive.

Also, Ovid is discussing the fact that most if-statements are of a form that would be better written as a switch statement. Additionally, switch statements, in Perl, are nearly always better written as dispatch tables. And, if you really want a dispatch table, try the following: 

my @dispatch = (
    [ sub { $_[0]->is_hungry }, sub { $_[0]->go_eat } ],
);

foreach my $choice (@dispatch)
{
    next unless $choice->[0]->( $self );
    $choice->[1]->( $self );
    last;
}

There's no rule that says dispatch tables have to be hashes of subrefs.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
