The not so low cost of calling dynamically defined methods
Ruby is great for metaprogramming, but what about the performance of calling metaprogrammed methods? We expect it to be on par with the equivalent ordinarily defined method but that’s not really the case as highlighted in this post.

If you’ve never used Ruby’s refinements, you might be surprised to learn that they’re lexically scoped. We’ll discuss what this means, and the implications for your code. http://blog.honeybadger.io/understanding-ruby-refinements-and-lexical-scope/

Luckily, we don’t need to reinvent the wheel, because this problem has been solved in a variety of ways. This blog post looks at one of those solutions, the acts_as_url library, and how it overrides Rails’ to_param method.
