S05: backslash+<alpha> in regexes should never be literal. about old-design-docs HOT 2 OPEN

This commit (7afa4fe) was in 2013; given that these are historical documents (and marked as such), is this worth fixing?

I'd rather see clear language added to docs.perl6.org if it's missing from there.

I just want to make sure that backslash+letter doesn't end up being interpreted as a quoted literal, in the sense that \j in a regex should be an error and not a way to match "j".

I recognize now that perhaps what the commit meant was that "\a" and "\x" in regexes match the same escaped characters that they do in double-quoted strings, but I didn't read it that way at first.

If the specs are purely historical, I don't mind if they're not patched, and I'll start looking to docs.perl6.org in the future I guess.
