I think we need a strong rationale in each individual case for why a 
particular interface in an installed header requires ({ }) to be 
implemented, rather than being able to use out-of-line code for compilers 
without that extension.  My expectation is that it's generally 
*ABI-related* extensions that we might be assuming support for in 
installed headers, not random other language extensions.
