vim's map()?  :-)

Hello,

  What is the counterpart in VimL of perl's map command?

  Here's an example of how the map command would be useful
  in VimL:

      As shown by the example in help inputlist():

        let color = inputlist(['Select color:', '1. red',
                                \ '2. green', '3. blue'])

      to effectively use inputlist([textlist]) one needs
      to massage the list in two ways:  prepend the list
      with a message such as "Select color:" and provide
      the index of each item in the list.

      I know how to do both the "massaging" in perl and for
      perl's lists:

          perl $i=0;
            \  @b = ('Select color:');
            \  push @b, map {$i++; "$i. $_"} qw(red  green  blue);
            \  VIM::Msg("@b");

      Unless there is a better way, VimL's insert() can be
      used to perform the "push" step above.

  But how would one do the "map" step above in VimL?

  Thanks,
