This took quit a bit of time to debug, There was nothing when searched tilde in the docs. Are there other characters like the ~ key that do not respect comments? Is this a bug or a feature?

Errors:
/*
~ten
*/

// ~ten

Not Error:
/~ten

… if you put a slash in front of it /~ten no error so its some sort of escape character???

* Note that the above looks like it has been commented out in the Vex editor window.

Here is an example of the error, note that the error does not report the line number correctly. Again making it hard to debug… wrong line… and two commenting out chunks of code does not help.

At first I thought there might be something off with your file itself because I don't get any errors when I do either of the following in a wrangle:


or


even both in the same wrangle doesn't give errors:


but if I take away the space between the first tilde and the forward slashes I do get an error:


Seems like the compiler may be a bit flakey in this regards, as I tried different combninations of spaces and no spaces - sometimes giving errors sometimes not.

As far as I know the tilde is used to get ones compliment.

Interesting that the tilde key and the backtick both share the same keyboard key. And since the backtick can be used in vex to access Hscript expressions;

Maybe the compiler in some cases is reading the tilde as a backtick which is creating problems?

Weird, and feels like a bug.
