Hi,  
I know how to dynamically create methods and classes in Ruby, but is  
there anyway to save these methods to a file?

eg. I’m looking for something like this:  
define\_method\_in\_file(“File.rb”, :myMethod) do  
instance\_variable\_set(:@a, “myString”)  
end

to produce:  
\<File.rb\>  
def myMethod  
@a = “myString”  
end

Thanks a lot for answering. I’m hoping there’s something easier than  
having to mess about with templates.
