Sourceval token_text : 'c p -> string
Sourceval trim_quotation : string -> char option * string

Utility function for the test returned by a QUOTATION token: It returns the delimiter parenthesis, if any, and the text without delimiters. Eg `{{ text

}

}

` -> Some '{', ` text `

for camlp5, eg GRAMMAR EXTEND ..... [ IDENT "x" -> .... ] END is a pattern (PIDENT (Some "x"))
