[Boost-users] PP: commas issues

Hi, I am trying to generate a list of instances of the same template with different pairs of args, to populate a mpl container, with PP so, mpl::vector< tmpl, tmpl, tmpl > i'm having trouble with the commas. I successfully generate the pp sequence (tmpl)(tmpl) (tmpl) but from this to get the enumeration, it's impossible using SEQ_ENUM, because the sequence contains commas MM
