How can I fix the template declaration to not error in that case?<br>

If you want to have a template parameter that can be anything, including a a symbol or a built in type, you can use this ugly workaround:<br>
<br>
template foo(bar...) if(bar.length == 1)<br>
{<br>
    enum foo = 1;<br>
}<br>

When you say &#39;anything&#39; though, does that include alias parameters? Will bar[0] be the equivalent of template foo(alias bar) if called with a symbol?</div>
