This morning block comments disappeared from the Decaf design. Maybe
later today they'll be instantiated in the tokenizer.

Out of the idlest of curiousity, does this language have a BNF, or
some other form of grammar definition?

Fortran (1957) had line comments. C (1972) replaced these with non-
nested block comments. C++ (1983) added here-to-EOL comments. Python
(1991) keeps here-to-EOL comments but replaces block comments with
multi-line quotes. Block comments and multi-line quotes both serve the
same purpose as doc

If you can only have one or the other, which is more helpful?

My 2 cents...
Thanks for the feedback, Bruno. Seriously thinking about ditching the
block comments and adding multi-line strings. (Block comments are the
last item on my tokenizer's todo list. Multi-line strings would be
easier.)
Beginners will be programming fun things in a GUI environment.

Should I have both? (Make a strong argument here: my design principal
is, Designed by a backpacker: when in doubt, leave it out.)

I'm afraid no one would use a language that didn't feature block
comments. However, inspection of a vast corpus of code might lead one
to believe that any commenting

I suppose we could argue semantics, since strings are actually
processed, but they are basically block comments.
So, there we are, multiline strings AND

Original languages were line oriented, newer languages were
block oriented.
Original languages has line comments. Newer languages had
block comments, and had line comments added back in.
So I would read that as line comments being more fundamental,
but people who used line comments got so sick
