以下のように、ripper が、メソッド名として " .bar" などといった  
空白やピリオドの入った文字列を取り出してくることがあります。

```auto
% ./ruby -v -rripper -e 'p Ripper.sexp("foo\n .bar")'
ruby 2.2.0dev (2014-10-22 trunk 48083) [x86_64-linux]
[:program, [[:call, [:vcall, [:@ident, "foo", [1, 0]]], :".", [:@ident, 
" .bar", [2, 0]]]]]

```

改行を入れなければ、“bar” という期待するメソッド名が取り出されます。

```auto
% ./ruby -rripper -e 'p Ripper.sexp("foo .bar")'
[:program, [[:call, [:vcall, [:@ident, "foo", [1, 0]]], :".", [:@ident, 
"bar", [1, 13]]]]]

```
