"Doesn't work"?

        print "The sum of 1 + 2 is ${\(1+2)}.\n";
-->
        The sum of 1 + 2 is 3.

I'm surprised your wouldn't have known this. The principle is the same:
"${...}" expects a scalar reference inside the block, and '\' provides
one. Of course, there shouldn't be a real multi-element list inside the
parens, but just one scalar. And often, the parens aren't needed.
