ludic.wallet

Money carried, in whole units: earned, spent only when it is there, lost when a cost happens anyway, and every change reported. Uses ludic.base and nothing else. Prices, reputation and what a thing costs are the game's; the wallet only holds the money.

import "ludic.wallet"

No ports: the wallet asks the world nothing.

API


`wallet_money()`, `wallet_can(n)`	what is there, and whether `n` is
`wallet_earn(n)`	add
`wallet_spend(n) -> bool`	only what is there: false, and nothing spent, when it is not
`wallet_lose(n)`	a cost that happens whether or not it can be paid (a rescue); never below zero
`wallet_set(n)`	exactly `n` (a starting purse, a correction, the network's word)
`wallet_changes() -> Queue<MoneyChanged>`	the facts: `{ before, after }`, one per change
`wallet_system() -> System`	`"wallet"`, `PH_COMMIT`: reset, and its save section (`wallet_save`, `wallet_load`)

Tests
