-Note that filling a 10x10 square of ``uint8`` + contract creation took more than ``800,000``

-3.14 million... well, there’s a pretty low ceiling for what you can create right

-Note that merely "creating" the array is free, the costs are in filling it.
-
-Note2: Optimizing storage access can pull the gas costs down considerably, because
-32 ``uint8`` values can be stored in a single slot. The problem is that these optimizations
-currently do not work across loops and also have a problem with bounds checking.
-You might get much better results in the future, though.

How do I initialize a contract with only a specific amount of wei?
