[Pdx-pm] subroutine calls CAN be string-interpolated!

[Eric Wilhelm]

And you thought they had to be concatenated with that messy 
quote-breaking " . thing($stuff) . " syntax.

  perl -e 'use constant foo => 7, 6; print "foo:  @{[foo]}\n";'

Is this undocumented or just obscure?

And even:

  perl -e '@f = (1,2,3);
  sub a {my @thing = @_; return(scalar(@thing));};
  print qq(foo: @{[a(@f)]}\n);'

Wow!  And I thought Ruby's "#{code goes here}" interpolation was 
something I couldn't do in Perl!
