Solidity

Modeling values with multiple variants, like a payment that's native ETH, ERC20, or ERC721, is typically done in Solidity with an enum and a struct holding every possible field, validated by require checks. Core Solidity's pattern matching offers an alternative.

Solidity Developer Survey 2025: AI trust vs. usage frequency 36% of daily AI users express distrust in the output. Nearly all who highly trust AI (37 of 38) are daily users. 88% adoption, 45% distrust. Developers adopt AI faster than they trust it.

And when a new payment type is added, the compiler reports every match expression that doesn't handle it, naming the specific missing case. The "did you handle X everywhere?" question becomes something the type system answers.
