Although it plays better with namespaces, I wonder if a macro would make
sense here:


Given that it works for all situations where needed, I see two (small)

1) Less overhead for the compiler, although it's probably already small
enough compared to some other boost libraries

2) The macro's all caps name is IMHO a better hint for the reader that
this is just a workaround for an unwanted compiler warning and not
something clever what the function-style might suggest.
