Yes, as an alternate syntax, interpolation works well to disambiguate your intent, which supports my point.  It&#x27;s really just a highly specialized form of a different operator, which says <i>I work on strings, so anything I see that isn&#x27;t a string coerce to a string</i>.  For example, in Perl<p><pre><code>    $varOne . $varTwo
</code></pre>
Is entirely equivalent to<p><pre><code>    &quot;$varOne$varTwo&quot;
</code></pre>
The question is why Scala chose to use + when it had other, non-ambiguous options, like above.
