问题 I tried this, but it didn't work: $*OUT.autoflush( 0 ); 回答1: $*OUT.autoflush = False should disable it, and it runs without error, but it seems that parrot's IO still flushes automatically.

Some examples from a long time ago mention an autoflush method, but that has disappeared: $*ERR.autoflush = True; $*ERR.say: "1. This is an error"; $

With perl5 without enabling "outflush" I don't get this behavior. 回答1: Rakudo enables autoflush by default; the specification is silent about the default. 回答2: Quoting from the docs regarding auto flush: ‘No global alternative available.
