The character ; should not be in the character set of symbol definition

[ngeiswei]

What is your problem?

One should not be able to use ; in a symbol, as it is expected to be the start of a comment.

How to reproduce your problem?

Run the following program

!(if True; my comment
     A
     B)

What do you get?

[(Error (if True; my comment A B) IncorrectNumberOfArguments)]

What would you normally expect?

[A]

What else do you have to say?

Other similarly looking languages such as Racket do not allow ; in symbols (I think).
