This is still incorrect, because it should be declarer name and not
declarer. To the best of my knowledge, we do not parse regular
expressions. The regular expression languages supported are those of PCRE
and those of the OCaml Str library, depending on how coccinelle is
configured at compile time. The PCRE regular expressions are more
standard, the OCaml ones are more old fashoioned.
