[rules-users] Retrieve values from a Map

[Wolfgang Laun]

If you need the value on the RHS, you can use s.th. like
   lang.get("Japanese")
or
   $c.getLanguage().get("Japanese")

If you want to match the value in a subsequent pattern, you
could use an eval() or similar; since you don't show what you
need the value for, I'll not enumerate all possibilities.
