//! Generates a comma separated list of shifted actual parameters.
/*!
In other words, expands to the sequence:

<PRE>\verbatim
  P##1, P##2, ..., P##N-1
\endverbatim</PRE>

NOTE: The implementation uses BOOST_PP_REPEAT().

RATIONALE:
- This macro facilitates a typical usage of the library. Shifted parameter
lists are common in template metaprograms.
