PP_LOOP is a pre-processor loop, so generates multiple blocks of code. For example:

PP_LOOP<5>(printf("hi");)()

Will compile as:

printf("hi");printf("hi");printf("hi");printf("hi");printf("hi");

The definition of this macro is:

PP_LOOP<loop count>(output)(separator)

The separator goes BETWEEN instances of ?output?, but not at the end. So you can make a list as:

PP_LOOP<10>(55)(, )

And that will compile as:

55, 55, 55, 55, 55, 55, 55, 55, 55, 55

Note the lack of ?, ? on the end because that?s not separating anything.
