:I got some clarification from Matz. The issue is with methods that take multiple arguments, and that's what may be disallowed in the future. I've reworded accordingly. Also, I've never seen a book recommend omitting brackets for multi-argument methods, so I've tightened that wording too. [[User:Metamatic|Metamatic]] 20:49, 16 May 2006 (UTC)
::In an expression like "puts Array.new 5, nil" the receiver of nil is ambiguous. In future versions such an expression will cause a syntax error. With "Array.new 5, nil" the receiver is not ambiguous so parentheses are not necessary. --[[User:Drbrain|drbrain]] 11:54, 18 June 2006 (UTC)
