My attempt - surprisingly short. Really annoying to test because every  
time you have a typo on a method name it offers to dynamically create  
the method for you!

I imagine it’s nothing too far removed from how everybody else is doing  
it.

module QAPrototype  
@@methods = Hash.new  
def method\_missing( name, \*args )  
puts “Undefined method " + self.class.to\_s + “.” +  
name.to\_s  
puts “How do you want me to handle this method? (end  
with a newline)”  
$stdout.flush  
method = Array.new  
begin  
line = gets  
method \<\< line  
end until line.eql?(”\n")  
@@methods[name]=method  
self.class.instance\_eval do  
define\_method(name) { eval(method.join) }  
end  
puts “OK”  
end

```
def print_defined_methods
	@@methods.each_pair { |key, value|
		puts key.to_s + ":"
		puts value
	}
end

```

End

I found an interesting thing when trying this in the runtime in SciTE -  
for some reason when ‘gets’ reads in a line, if you made a mistake  
whilst typing and backspaced to delete some text and re-write it, then  
the string that ‘gets’ returns includes the deleted text. Anyone know  
why this might be?

Is that a typo? Should be “end” I assume.
