Add interpolations to regex sets

This commit adds the capability for '(?[ ])' to contain interpolated
variables from other '(?[ ])' constructs.  A set operation can thus be
built up from the composition of other ones, without having to worry
about precedence, etc.

Thanks to Aaron Crane for suggesting this.
