Can't we do that already?

If you need more scope, use constants.

It is not the same, because you include the textual data (it is somehow like usind the C preprocessor). There
are two disadvantages:

1) During debugging or things like this you don't see your constructed structure - you have to work with the
final regular expression

2) You cannot manage recursive constructs, which are possible using '\g<name>'. This is a standard part on
Oniguruma.
