Subject: String#decorate

When chaining methods, it'd be neat to have something that was passed
in the string and returned a 'decorated' version, e.g.

pp = ary.join(",").decorate {|s| "[#{s}]"}
attrib = title.capitalize.decorate {|t| "\t -- #{author[t]},\"#{t}\""}
(n*100).to_s.decorate {|p| "#{p}% done"}

as opposed to equivalents using String#+ and String#=, or even the
fully functional but just a trifle ugly String.gsub /.*/ {|s| ...}

Not quite an RCR (it's trivially implementable anyway) - just wanted
to see what people thought of the idea, and in particular if anyone
had nicer names to suggest.
