Sebastian,

I think to get the desired effect will need to use BOOST_PP_INTERCEPT to
suppress the number:

BOOST_PP_ENUM_PARAMS
<http://www.boost.org/doc/libs/1_49_0/libs/preprocessor/doc/ref/enum_binary_params.html>(5,
SomeText BOOST_PP_INTERCEPT
<http://www.boost.org/doc/libs/1_49_0/libs/preprocessor/doc/ref/intercept.html>)

Regards
Daniel Bradburn
