noob solidity question… if I have a struct that looks like this:

struct Special {
    string name;
    address[] deals;
    mapping (address => string[5]) dealNames;

how can I initialize a new "Special" with an empty deals array and empty dealNames mapping, having only a string for name.

I've tried this and it errors out (obviously?)

Special special = Special({
    name: "bingo",
    deals: [],
    dealNames: {}

You can initialise the Struct like this:

address[] memory addresses;
Special memory s = Special("Test", addresses);

There a section in the FAQ of the Solidity documentation that you might also find useful.
