unfortunately no, but good idea nonetheless ... :)

  DB<39> x @input
0  2
1  7
2  11
3  15
  DB<40> use experimental 'refaliasing'; \$input[1] = \$input[-1]

  DB<41> x @input
0  2
1  15
2  11
3  15
  DB<42> for my $v (@input) { say $v if \$v==\$input[-1] }
15

  DB<43>

I'm not even sure that experimental feature is even needed...

IIRC one could somehow use typeglob aliasing on array elements.
