How to get Year + Month with Locales

[Tatsuhiko Miyagawa]

How can I get "Year + Month" with DateTime::Locale framework?

All I want is a string for a valid year-month, like:

  January, 2006 (en_US)
  2006 年 1 月 (ja_JP)

Neither of available formats like lond_date_format, full_date_format
and medium_date_format suffice my need.

Thanks,
