Backport #7983: Fixnumの演算子がprependでオーバーライドできない

• Status: Closed
• Priority: Normal
• Assignee: nagachika (Tomoyuki Chikanaga)

[tera (yuki teraoka)]

=begin
Fixnumの演算子をprependを使ってオーバーライドしても、適用されない。

sendで実行した場合はprependしたmoduleのメソッドが実行される。

【再現手順】

module M
def /(other)
to_f / other
end
end

Fixnum.send(:prepend, M)

1 / 2 #=> 0
1.send(:/, 2) #=> 0.5
=end
