Symbolic refs will do instead of eval.
{
no strict 'refs';
my $name = 'Foo::some_sub';
print B::svref_2object(\*$name)->LINE;
print B::svref_2object(\&$name)->GV->LINE;
$name->();
}
It can be done with strict refs too.
my $glob = $::{'Foo::'}{some_sub};
print B::svref_2object(\*$glob)->LINE;
print B::svref_2object(\&$glob)->GV->LINE;
$glob->();
