[swift-evolution] Should be able to initialize list of lists with 2d static data without unexpected errors.

[Amir Michail]

It’s very irritating trying to initialize a list of lists with static data and unpredictably encountering expression too complex errors.

One could then try to incrementally initialize such a list of lists with append for each row say.

Such initialization with simple 2d static data should never result in an expression too complex error.
