Updated by nobu (Nobuyoshi Nakada) about 10 years ago
This raises a NoMethodError in ruby 2.2.0preview1: ruby -e "class A; define_method('b='.to_sym){|v|}; end; A.new.b = 1" This does not, showing it is specific to dynamic symbols: ruby -e "class A; define_method(:b=){|v|}; end; A.new.b = 1" This does not, showing it is specific to symbols ending in =: ruby -e "class A; define_method('b'.to_sym){}; end; A.new.b" This does not, showing it works when called via send: ruby -e "class A; define_method('b='.to_sym){|v|}; end; A.new.send(:b=, 1)" This does not, showing it works after calling send: ruby -e "class A; define_method('b='.to_sym){|v|}; end; A.new.send(:b=, 1); A.new.b = 1" I apologize if this is already fixed in trunk.
