Not sure... I don't think there are that many Boost libraries that  
use Boost.Parameter so I don't believe that you'd have that too many  
conflicting defaults.

Successive redefinition between compiled files but it probably won't  
work within the same translation unit. You'd have to undef all the  
header guards, and that's probably going to result in some serious  
violations of the ODR (one definition rule).

I'm probably going to end up overriding the default in my include  
chain, but I think the best solution may simply be to change the  
default in Boost.Parameter.
