What's wrong with old-fashioned autoextending array slices that
now DWIM
splice @foo,@foo,4,readline(STDIN);
Getting splice to coerce that reference that @foo is returning
into it's length method is all behind-the-scenes; this is
a toenail-trimming incremental improvement which would break
any very strange code which did exactly that and expected readline
in an array context to wipe out the rest of the stream. I've
got $2.37 for the first person to produce a piece of code not
contrived as an example where a slurp in a splice is used.
