Repeated use of an attribute about cro-webapp HOT 2 CLOSED

It was never really intended that one could interpolate tag names. It does - far more by accident than design - work out for opening tags, however I suspect that will cease to work with the most obvious implementation of #44. For closing tags we simply never try to parse inside of them and thus end up confused.

I've mixed feelings about supporting this; I really want structured tag support as requested in the referenced issue, but supporting interpolating into HTML tag names will significantly complicate it.

FWIW, I found a workaround using a sub.
For the example I was needing:

<:sub heading($level=1,:$close=False)>
<?$close>/</?>h<$level></:>

<<&heading(.level)> id="<.target>">
<a href="#<.top>" class="u" title="go to top of document">
<.text>
</a>
<<&heading(.level,:close)>>
