Isn't this rather complicated?

In this case, has there been any progress on "single line" comments eg

// some comment

? I think this was mentioned recently on the list. (I am also aware that //
is verboten for some reason).

It seems to me that multiline comments are a poor design choice. Single
line comments permit commenting arbitrary blocks (just prepend each line
with "//"), and play well with nested comments (no problem if a line starts
"// //" etc). Also, they are very simple to implement in the lexer.

Please can we have support for simple (ie from the token "//" to the
end-of-line, no messing with string literals etc) single line comments?

Thanks
