using `#` in an elision seems to break the binding

[thedavidmeister]

seems like a similar issue to previously where ' would break comments, looks like a # in an elision message breaks out of the elision message

[rouzwelt]

this is not an issue, using # or @ or other reserved chars that are meaningful for parsing will cause the parser to consider them as bindings or imports, so those chars are not allowed to be used in the elision msg
