Not answering your question but in the spirit of TIMTOWTDI, just having a play with recursion for the fun of it.

johngg@shiraz:~ > perl -Mstrict -Mwarnings -E '
my @arr = ( 1 .. 10 );
recPrint( @arr );

sub recPrint
{
    @_
    ? do {
         say join q{ }, shift, qq{@_};
         &recPrint;
      }
    : return;
}'

Using a while loop is the obvious and simplest way to go though.
