In other words, expands to the sequence:
|
|
|
|
<PRE>\verbatim
|
|
P##1, P##2, ..., P##N-1
|
|
\endverbatim</PRE>
|
|
|
|
NOTE: The implementation uses BOOST_PREPROCESSOR_REPEAT().
|
|
|
|
RATIONALE:
|
|
- This macro facilitates a typical usage of the library. Shifted parameter
|
|
lists are common in template metaprograms.
|
|
- ENUM_SHIFTED_PARAMS must be tested so that the shifted range is shown to be
|
|
correct.
