"ExpressionError: invalid syntax" on "<" about chameleon

[malthe]

Is this also on Chameleon 2.2?

Because I've fixed another issue with the escaping of these characters
and that fix is included in 2.2.

Here's the TB if I use "<" and ">"::

I've tried various combinations of ">", "<", ">", "<", "lt" and "gt", all of which work without Chameleon but only "lt" and "gt_" work under chameleon.  I'm using that workaround for now so I'm fine if you just want to close this ticket, but it is an incompatibility and I thought at least I should document it.

When I revert my workaround and use Chameleon from git and five.pt/trunk, I still get the error with Chameleon and not without.
