----------------------------------------
以下のように、a / b c という内容のファイルを
ruby -c で検査すると syntax error になるのですが
Ripper.sexp に適用するとなにか構文木が返ってきます。

```
% cat z.rb
a / b c
% ./ruby -c z.rb
z.rb:1: syntax error, unexpected tIDENTIFIER, expecting keyword_do or '{' or '('
zsh: exit 1     ./ruby -c z.rb
% ./ruby -rripper -e 'p Ripper.sexp(STDIN.read)' < z.rb
[:program, [:vcall, [:@ident, "c", [1, 6]]]]
% ./ruby -v
ruby 2.2.0dev (2014-10-20 trunk 48052) [x86_64-linux]
```

これは変な気がするんですがどうでしょうか。
