FreeMarker wasn't designed with JSP in mind... the whole JSP support
was an extension added later that technically could have been 3rd
party as well. I mean, it doesn't affect the core. And so come the
miss-match: the name-like part in a FreeMarker @ tag is a free form
expression, not just a name like in JSP or in XML. Hence dash means
subtraction. The workaround is that instead of this:

  <@ui.panel-container />

you write this:

  <@ui["panel-container"] />

Ugly, but works.

As of the future, I think it could be addressed. Since the result of a
subtraction is always a pure number, and you can't call a number, the
parser could be smarter and guess the intent. Dirty, but sounds
useful...
