< div style = "margin-left: 0px;" > The < b > BOOST_PP_ARRAY_ENUM</ b >
macro converts an < i > array</ i > to its comma-separated elements.
The comma-separated elements are in the form of < i > variadic data</ i > .< br >

< h4 > Remarks </ h4 >
< div > This macro expands to a comma-separated list of the elements
in < i > array</ i > .
For example, < b > BOOST_PP_ARRAY_ENUM</ b > ((3,(< i > x,</ i >< i > y,</ i >< i > z</ i > )))
expands
to...
< div > < i > x</ i > , < i > y</ i > , < i > z< br >
</ i > </ div >

< i > data</ i > will be empty.</ p >
