Mount default language at root _and_ in subfolder

I have a multilingual site and would like to mount the default language (English) at root, but also make it available with the /en prefix. Is this possible ?

Thank you,

Guillermo

Doesn’t seem to be supported in the docs, but you can hack it, the ugly way: duplicate the /locales/en.yml as something different, ie. /locales/en2.yml and then mount_at_root: :en2 in config. But if you plan to use separate templates for different languages, this might be unpractical, unless automated in the before_build step in config.rb.
The other way is to try redirects. I haven’t used/tested any of these ideas (except for using before_build for other similar purposes.
