## [It would be nice to import a library, another contract's interface, or a

## [Declare a positive number] Why change the type from `uint256`? `num` is

## Also, will 4-byte identifiers be compatible with solidity?
## ie. `bytes4(keccak256('uint256'))` or `bytes4(keccak256('num'))` ? Or is

Very cheap to deploy (66k gas) forwarder contracts that can clone any contract and still have their own storage

// Credits to Jordi Baylina for this way of deploying contracts https://gist.github.com/jbaylina/e8ac19b8e7478fd10cf0363ad1a5a4b3

// Just 66349 gas per contract

This is a first draft at what could be a continuous token sale. I just wrote it and haven't tested it but it shows the proof of concept: tokens are continuously generated in any curve desired and sold for the highest bidder. Since there's a maximum token sale speed, this guarantees that sales can't end too quickly. Since the sale always starts f…
