## 1. Common Standard Library Patterns
```move
// Strings — use method syntax, don't import utf8
let s: String = b"hello".to_string();
let ascii: ascii::String = b"hello".to_ascii_string();
// Coin and Balance
use sui::coin::{Self, Coin};
use sui::balance::{Self, Balance};
let balance: Balance<SUI> = coin.into_balance();
let coin: Coin<SUI> = balance.into_coin(ctx); // ✅ method syntax
let amount: u64 = coin.value();
// Split a payment
let exact = payment.split(amount, ctx); // ✅
let exact = payment.balance_mut().split(amount); // ✅ avoids ctx
// Consuming values without `drop` — the @0x0 burn pattern
//
// Move's linear type system requires every non-`drop` value to be
// explicitly consumed. The `_` prefix only suppresses warnings for values
// that *do* have `drop` — it won't help for Balance<T>, Coin<T>, or your
// own structs that lack `drop`.
//
// To permanently destroy any `key + store` object, transfer it to @0x0
// (an address no one controls, equivalent to Solidity's address(0)):
transfer::public_transfer(my_obj, @0x0); // ✅ permanent burn
//
// Balance<T> has neither `drop` nor `key`, so it cannot be transferred
// directly, and `balance::destroy_zero` only works on empty balances.
// Wrap it in a Coin first:
//
// let _locked = supply.increase_supply(MINIMUM_LIQUIDITY); // ❌ compile error
//
let locked = supply.increase_supply(MINIMUM_LIQUIDITY).into_coin(ctx);
transfer::public_transfer(locked, @0x0); // ✅ burns the minimum liquidity
//
