Thanks for that link. Yes, that is close. I'd even feel reasonaly 
well about it if it was in phobos so everybody can use the 
mechanism consistently.

It does not however, quite meet the mark of "with ease". But it 
is possibly an acceptable hack around a shortcoming in the 
language. Comming from C++, it's not as though I'm not used to 
those. Just a shame to have to resort to it when D is so pretty 
close to getting rid of dirty hacks more or less completely.

Cheers,
Seb
