Is there a better way? Any reference to the cases where it will fail?

[merlyn]

It will fail on this:

my $increment_by_secret = do {
  my $secret_number = 7;
  sub { $secret_number + shift };
};

It fails because there's no access to $secret_number from outside the coderef, so we can't tell what the "magic constant" should be. All you get is:

{
    ($secret_number + shift(@_));
}

(Just tested.)
