Hello folks,

## I’m playing around with dynamic monkey-patching of methods. However, I run into syntax errors of my generated code: ruby monkey.rb Two: unpatched

Patched test\_two called  
Two: patched  
monkey.rb:12:in `catch_method': (eval):4:in `catch\_method’: compile  
error (SyntaxError)  
(eval):3: syntax error, unexpected ‘,’, expecting ‘=’  
old\_test\_attribute=(\*args,&block)  
^  
from monkey.rb:33

Do you know a way for dynamic monkey-patching of getter / setter  
methods?

Try using send:

send(:foo=, \*args, &block)
