Scope

A chain of compile-time variables (@let).

class MMO\client\scs\Scope

Namespace: MMO\client\scs

Lookup walks up to the parent scope, declaration always happens locally: a `@let` inside a block therefore shadows the outer variable of the same name instead of overwriting it (`the` spec, 38).

$global = new Scope(); $global->define('spacing', Value::Number(16, 'px')); $local = $global->child(); $local->define('spacing', Value::Number(24, 'px')); // the local one wins inside $local only
