My vote is to ditch the concat operator altogether. Hey, we have
interpolation!

        "$this$is$just$as$ugly$but$it$works"

Which reminds me... one problem I have with it is that it's too hard to
separate a variable name from the rest of the string, if it also
consists of word characters:

        my $bar = "BAR";
        print "foo${bar}baz";  -> fooBARbaz

Since $bar is a lexical variable, this syntax doesn't make much sense
anyway: it reeks of symbolic references and those don't work for
lexicals.

I think I'd like something incorporating a backslash would be nicer:

        print "foo$bar\Ebaz";

It works, but it may have unwanted side effects -- in case the "\E"
actually serves a purpose.

But, you may completely forget about it. I just had to say this one day.
