Ruby

Bug #11983

Updated by nobu (Nobuyoshi Nakada) over 10 years ago

## Steps **Steps to Reproduce: Reproduce:** 

 Inside irb: 

 ~~~ruby 
 Class A 
 end 

 A.send(:define_method, "may_run!?") do |*args, &block| 
   p "random text" 
 end 

 a = A.new 

 a.may_run!? 
 ~~~ 

 * never return from this function. 

 ----------------------------------------------- 

 IF I try to declare this function using `class_eval` 

 ~~~ruby 
 class_eval  

 A.class_eval <<-EQRUBY 
   def may_run!? 
     p 'some text' 
   end 
 EQRUBY 
 end 
 ~~~ 

 I got error: `syntax syntax error, unexpected '?', expecting ';' or '\n'`. '\n'. 

 I think `class_eval` class_eval behaviour is right because `may_run!?` may_run!? is invalid name for method and `define_method` define_method should raise error instead of defining it.
