in thread Extend regex legibility within character classes

That's what I started with, but wanted to get rid of the extra named variable. Using the @{[]} trick lets me write it in one statement.

The extra variable would be less objectionable if I could hide the scope, but if the real one I'm declaring is also a "my", I can't put braces around the whole thing. It would take a third line, outside of the braces, first to declare it.
