Are you meaning add an extra syntax to conveniently output "<!-- comment -->" or a comment that only exists in the hamlet template and not within the generated html output?

The former seems less useful, on the rare occasion "<!-- comment -->" is required I will type it directly. This would seem like a waste of syntax if it didn't get used enough.

For the latter though why can't you make regular double dash '--' as the comment to maintain consistency for when the hamlet is written quasi quoted within haskell source? (Currently it ends up in the generated html).

Thanks
