They can indeed: when I put together the TR1 library in the sandbox vault 
(http://boost-sandbox.sourceforge.net/vault/index.php?&direction=0&order=&directory=tr1), 
I wrapped all the random generators in order to provide a TR1 conforming 
interface: no fancy compiler tricks were required at all.  Feel free to 
steal any code you want.

Footnote: strictly speaking these changes which introduce new features 
should not have been introduced at this time (right before release).
