37. Vyper vs Solidity: design philosophy

Solidity optimises for expressiveness and developer familiarity (inheritance, modifiers, operator overloading in some contexts, assembly escape hatches). Vyper optimises for the reviewer: fewer ways to write the same thing, no hidden control flow, and compiler-enforced explicitness (visibility, bounded loops, no inheritance).

# Vyper favours one obvious way to write access control:
assert msg.sender == self.owner, "not owner"

// Solidity offers several equally valid styles:
// modifier onlyOwner() { require(msg.sender == owner); _; }

Neither is strictly 'better' — Vyper suits contracts where minimizing audit surface is the top priority, while Solidity's ecosystem (tooling, libraries like OpenZeppelin) is larger and more mature.
