Comment (by renficiaud):

 Thanks for the clarification. The problem with {{{__COUNTER__}}} is that
 it is not a standard macro, I would rather not include that. Also since
 those registrar are static, there is no clash in having the exact same
 declarations (in terms of lines) in 2 different compilation units, if you
 do not include everything in one place.

 That is to me a really specific use case, and also has the following
 drawbacks:

 * each time a .cpp changes, a very big block is recompiled
 * you do not benefit from potential accelerations of the build system (//
 builds)

 I am not sure the benefits of doing it the way you do outweigh the
 problems (maybe you have numbers). I would rather suggest a nasty patch:
 you can specify a line number with the {{{#line}}} preprocessor directive,
 which may be used in conjunction with {{{__COUNTER__}}} in your case to
 lower the risks for clashes.
