Hi Loops,

Thank you once again.

I haven't yet tested your version, but have spent some time reading / understanding its functionality. It appears to be a much more elegant solution. I particularly approve its ability to try to do the right thing when a selectee is blank / missing, this will be beneficial in shortening long url query strings, I now wonder if its possible to do something similar with repetitive hash keys. I also thought the block handling the += was nicely thought out, I was unable to come up with a one line notation myself, though I will probably combine the push to remain consistent with the corresponding if. Finally, due to using an outdated Perl version, I will have to write an alternative to the regexp r flag (handle in two steps, or use do).

I will have to perform vigorous testing and get back to you if I have any outstanding concerns, but this was exactly what I needed, you've killed two birds with one two stones between your two replies, I'm very grateful for your expertise and time. I'm also working on an _undive function (reverse dive / ref to selector), which is proving to be tricky, but I'm getting there.

Chris
