ささだです． 以下の件，初めて見るんですが，詳しい仕様ってどうなってます？ 1. multiple splats を「どこで許す」んでしょうか．多重代入だけ？ splat が書ける，どんなところでも？ 2. コンパイルは，「*a, b, *c」 -> 「*(a.splat + [b] + c.splat)」でいいん でしょうか． 3. どういう構文木になるんでしょうか Yukihiro Matsumoto wrote: > Hi, > > In message "Re: Ruby 1.9: multiple splats on rvalues in parallel assignment" > on Thu, 26 Apr 2007 03:07:09 +0900, David Flanagan <david@davidflanagan.com> writes: > | > |I've confirmed this bug against the current trunk: > | > |ruby1.9 -ve 'x,y,z=1,*[2],*[3]; p x,y,z' > |ruby 1.9.0 (2007-04-25 patchlevel 0) [i686-linux] > |[1] > |3 > |nil > | > |My question (for Matz or Nobu?) is about the nature of the bug.
