Subject: Re: Run some method based on some condition

Something like this would work:

irb(main):008:0> x = ['chop!', 'chop!', 'chop!']
=> ["chop!", "chop!", "chop!"]
irb(main):009:0> y = "This is a string!!!"
=> "This is a string!!!"
irb(main):010:0> x.each {|method| y.send(method)}
=> ["chop!", "chop!", "chop!"]
irb(main):011:0> y
=> "This is a string"

The send method allows you to do what you're asking. :)
