I was directed to [1], section "Extracting submatches
from a regex match", so I put together

    (let ((header "From: Joe Hacker <get@this.data>"))
      (save-match-data
        (string-match "<\\(.*\\)>" header)
        (match-string 1 header) )) ; => "get@this.data"

Maybe my original solution to that particular problem
is just as good, but I asked for a generic way and
this seems to be it.
