OK gotya. But -1 still doesn't feel right. I prefer your defaults:

repeat<0>(a);      // zero or more
repeat<1>(a);      // one or more
repeat<0, 1>(a);  // zero or one
repeat<8, 8>(a);  // exactly 8 (a bit awkward but will do)

repeat? loop? iterate?

Hey how about variable repeats? I encounter many times
when parsing files and streams that the size of *something* is 
prefix encoded. Example:

   string_length
   iterate(string_length){  char  }
