That is the dirty secret of message-passing concurrency: the compiler never told you that two actors could touch the same mutable state, because in most languages it <em>cannot</em> tell you. Pony was built to close that hole — every reference in Pony carries a <strong>reference capability</strong> (<code>iso</code>, <code>val</code>, <code>ref</code>, <code>box</code>, <code>trn</code>, <code>tag</code>) and the compiler rejects any program where a data race is structurally possible. No locks, no <code>synchronized</code>, no runtime race detector needed: races become type errors.</p>
