Why the switch to vyper? about v1-contracts

[haydenadams]

Vyper is awesome - built in overflow/underflow protection, extreme readability, pythonic, some re-entrancy protection, easy testing. The TLDR is that it forces best practices, something severely lacking in the smart contract space. And It only took a few days to port over the entire smart contract from Solidity. The original move was suggested by Vitalik.

I felt comfortable moving to Vyper since at the time the EF was building Casper in a Vyper contract (Casper is no longer a smart contract). B/c of this, there was a big push from the EF that massively improved the Vyper codebase to the point where it was (mostly) ready for production contracts. I thought Uniswap could be a good project to demonstrate the Vyper's capabilities, and might gain some press as well.
