# # Switzerland (simplified):
# #
# country('41', fixed(2) >> local([3,2,2]))
#
# # Germany. Too big, we use a separate file:
# #
# Phony.define do
#   country '49', match(...) >> split([...]) ||
#                 one_of([...], :max_length => 5) >> split([...])
# end
#
# # Denmark:
# #
# country('45', none >> split([2,2,2,2]))
#
# # Hungary:
# #
# country('36',
#         match(/^104|105|107|112/) >> split([3,3]) ||
#         one_of([1], :max_length => 2) >> split([3,4])
# )
#
# Note: Perhaps the DSL should operate directly on country codes.
