Dunno, never tried them, but if they don't work together it's a bug that
should be fixed.

Yup, but if you swap the order of these two plugins, ::PathPrefix can act
before ::Request (and, BTW, ::PathPrefix also acts before the dispatcher,
these two modules hook to the same method:-).

Can you try if it works if you simply change the order of
loading ::Request and ::PathPrefix? (If it works then I'll update the
documentation to mention it.)

Nope, ::Request uses $c->localize(), and that uses $c->languages(), and
C:P:I18N::PathPrefix sets that to the language from the path prefix. So
they should work together smoothly (given that ::PathPrefix has the
first turn).

You can achieve that using C:P:I18N, C:P:I18N::PathPrefix and
C:P:I18N::Request together. Also you don't need a session for that: if
the user uses an URL to your site with a language code path prefix, that
language will be used throughout the site until (s)he switches language,
if (s)he uses an URL without a language code path prefix then it will be
set from the 'accept-language'. Alternatively you can set a plain cookie
if you want to remember the preferred language from the previous
"browsing session" and if (s)he uses an URL without a path prefix you can
use the value of this cookie to override the language detected from
