CommentChar::
   SourceCharacter but not LineTerminator

GraphQL source documents may contain single‐line comments, starting with the # marker.

A comment can contain any Unicode code point except LineTerminator so a comment always consists of all code points starting with the # character up to but not including the line terminator.

Comments behave like white space and may appear after any token, or before a line terminator, and have no significance to the semantic meaning of a GraphQL query document.
