Would be nice to get list, setand map

[coopernurse]

Hi there. Lists are supported already using []. Maps would be possible assuming the keys are always strings (as required by JSON). How would you expect sets to work?

hey! True, i got away with the [] and struct for map. Not sure about set, but i was wondering why and how hard would it be to implement those idl types?

ps: i started to work on a barrister-amqp FYI: https://github.com/gregory/barrister-amqp
