if i understand you correctly what you ask for is an implementation of 
regEx as in Ruby.
Ruby is totally OOP and RegEx is OOP based so we have classes an such to 
represent the expression and the results, etc..
on top of it it implement an interface wich allows you to use regEx as 
you would normally expect (like in perl. for example you can use literal 
expressions like /pattern/).  most of the time people use that. you can 
use the underlying classes if you want but that of course is more 
verbose (and probably most of the time is not needed).
This is much better than two code bases, it gives us the benefits of 
both styles and i think that's what lars suggests.
the only thing left to do is figure out how a similar structure could be 
implemented in D.
