RFC for comment sigils

[bburns]

Just an idea, could comment out a line/block by prefixing with ~. This would roughly correspond to a possible strikethrough representation.

Why comment out lines/blocks?

I often want a way to do this quickly in notes, to keep around things I want to disregard, or color differently, eg grayed out.

In orgmode can do with #, which matches shell and python, but conflicts with the heading sigil.

In markdown, have to use html comments <!-- foo -->, which is obviously very awkward.

Alternatives - ; as in lisp, ' as in basic, ! as in fortran (nah).
