Sure, you can use eval, eg.

irb(main):002:0> eval 'puts "Hello world"'
Hello world
=> nil

However, eval should be usually avoided. Instead Ruby has the methods
instance_eval, class_eval and module_eval, which works the same as
eval but the argumented is executed in the scope of the current object/
class/module.
