Why not make slash_1, slash_2, etc. class constants?

scribu commented

Also, I think it would be less confusing if meta keys matched slash values:

wp_add_post_meta( $id, 'slash_test_1', $this->slash_1 );
wp_add_post_meta( $id, 'slash_test_2', $this->slash_2 );
wp_add_post_meta( $id, 'slash_test_3', $this->slash_3 );

I heard that you don't get comment notifications for gists anymore, unless I mention you, @alexkingorg.

Man, still didn't get any notifications - just happened to poke back in here. The tests run even and odd slashes in groups specifically.
