Ah, I didn't know this. In which case you should be able to store 
nparams for use later when the array is encountered, then parse as 
appropriate?

static nparams = 0;
foreach( m; MyStruct.tupleof )
{
   static if( is( typeof(m) x : x[] ) )
   {
     parseParams(nparams);
   }
   else
   {
     static if( MyStruct.tupleof[i].stringof[$-7 $] == "nparams" )
       nparams = m;
   }
}
