Single-line comments wanted

[hrissan]

This is pf course mnor, but it is so verbose and annoying to type text below to add simple note to myself.
I've ended up commenting my templates way less than I'd like.

{% comment %}
This is a comment.
{% endcomment %}

Can you plesae invent some terse statement for single-line comments?

{% // This is a comment.

Or if you think there must be closing tag, then

{% // This is a comment. %}
