Suggestion about commenting for future TAL versions

In TAL making comments is pretty heavy and HTML syntax highlighters don't detect 
comments. Because commenting is such pain lazy people (like me!) might skip it.

E.g.

<tal:comment replace="nothing">
       A long long string before comment begings and comment ends
</tal:comment>

I'd suggest that TAL could use modified HTML syntax comments. 

<!---
   
   A comment goes here


 -->


Difference between a comment which appears in the final HTML and a comment which 
is dropped out when applying the template is the number of dashes <!-- and <!---
