As far as I am concerned, Rails try to be as clear and readable as possible in the means of DSL practices. They give the developer all tools for his code to be read like English. We even have aliases like “days” and “minutes” to “day” and “minute” to make forms like 5.days to be read more naturally.
Writing something like “is_a? Integer” doesn’t sound really euphonic to my ear and mind. “is_an? Integer” sounds much better.
Is it OK to submit such a pull request as a part of ActiveSupport core extensions?
