Hi Dear Author
Would you add C like comment to your mini formula language? It will be useful for long expressions, such as ...
// Symbols
s1 = "IC2309";
s2 = "IH2312";
s3 = "IF2309"
s4 = "IC2312";
// Inputs
my_ask = future(s1, "ask");
my_bid = future(s2, "bid");
my_mid = (my_ask + my_bid) / 2;
my_last = future(s3, "price");
my_ask *= 1.0001;
my_bid += 0.0005;
my_bid2 = future(s4, "bid") * 1.0002;
// Ouput
M1 = (my_ask, my_bid, my_mid, my_last);
M2 = (my_ask, my_bid2, ...)

Comment support is a great idea, and should not be too difficult. My
resources to work on this crate are limited though, so I would be happy
about a pull request.
One would add this somewhere in the tokenizer, where, whenever a `//` is
encountered, the tokenizer just skips until after the next newline
character.

Oh, cool, I will do it, the idea is adding C like comment, /* inline comment */
and // single line comment
. I am so glad that you are agree with that, I will make a PR later, thanks!
