この案の欠点は [] なら引数パターンで指定できるものが、いちい

でしょうが。

|Ｂ案）ちょっと革新的な案

|	delete(e)		eに一致する最初のものを削除
|	delete!(i)		i番目を削除

この案の問題は delete と delete! で引数の意味が違う点ですね。
これは私にとって大きな大問題です。

「引数の意味」の点でB案は採用できません。A案はうーん、ちょっ
と悩むところですね。

C案) slice/slice!を導入。delete_atは現状のまま
D案) slice/slice!を導入。delete_atはslice!と同じ
E案) slice/slice!を導入。delete_atは近い将来無くす

の方が受け入れやすいですね。
