Subject: [ruby-talk:23237] Parsing Ruby's interpolated strings/regexps

Hi,

What would you expect a Ruby parser to return after parsing an
interpolated string or regexp like for example

/a#{b+1}c/

?

Matz Ruby interpreter currently parses this into

Newline(Dregx("a"
              Array(Evstr("b+1")
                    1
                    Array(Str("c")
                          1
                          nil))))

and then recursively parses the Evstr "b+1" when in evaluation of the
program with the regexp.

But if you have a separate parser (ie. not bound to a special
interpreter) would you expect the "b+1" string to
have been parsed in the Abstract Syntax Tree you get back?

Thanks,

Robert
