Hello,
It seems that BOOST_PP_SEQ_SIZE generates a warning with empty sequences under MSVC (vs 2010/boost 1.46.1).
There is no such a thing as a truly empty sequence: http://www.boost.org/doc/libs/1_46_1/libs/preprocessor/doc/ Although you can kinda fake it through BOOST_PP_SEQ_NIL. [...]
More general question:
I'm discovering boost. I'm really impressed by the macros in boost/preprocessor. It makes a lot of things possible.
Indeed.
But it provides features the preprocessor was not meant for. For that, it uses a lot of tricks.
Indeed. And a lot of workarounds for broken preprocessors. How portable is it?
How many architectures is it known to work/not work with?
I know the authors went to great lengths to make the library relatively portable, but there *might* be some ancient compilers for which some parts of the library are broken, I don't know.
Can we be confident that it should work with any preprocessor?
Certainly for any standards-conforming preprocessor, and certainly not for an arbitrarily-broken preprocessor :) Thanks for your help.
