/\*/ という、間違った regexp リテラルは  
ruby -c ではちゃんとエラーになるのですが、  
Ripper.sexp ではエラーになりません。

```auto
% cat z.rb
/*/
% ruby -c z.rb
z.rb:1: target of repeat operator is not specified: /*/
% ruby -rripper -e 'p Ripper.sexp(STDIN.read)' < z.rb
[:program, [[:regexp_literal, [[:@tstring_content, "*", [1, 1]]], 
[:@regexp_end, "/", [1, 2]]]]]
% ruby -v
ruby 2.2.0dev (2014-10-27 trunk 48168) [x86_64-linux]

```

Ripper では regexp object を作らないからでしょうが、  
syntax error を調べる目的に対して不都合ではあります。
