"Regex and interpolation is a bit confusing"

[zoffixznet]

A user had trouble understanding the section on interpolation in regexes.

I glanced at it, and it's a giant codeblock that shows a lot of irrelevant stuff, like .flip inside $(...) coercer. The <{...}> form also looks out of place and probably belongs in the section about blocks.

IMO that section could use a bit of cleanup and organization.

The space before "regex interpolation" does not make a lot of sense... We'll take a look at it, thanks for raising the issue.

It may still need reviewing again in the future, but hopefully now works a bit better

Reopened because #2599

Can this be closed now?

[JJ]

Well, there's #3705 and some others. I wouldn't close it without a thorough revision and checking if there are any other outstanding issues, anyway.
