Huh.  My gut tells me this is a total hack, yet my brain doesn't seem
to be able to poke an honest hole in it, other than the complications
in implementing the reader.  Does it scale to multiple arguments?

$data = foo(<<THING1, <<THING2, arg3, arg4);
This is the value of THING1
This is the value of THING2
