"For example, Pyret trades performance for mathematical familiarity by using exact representations of rational numbers as its primary number type." (Disclaimer: I haven't used Pyret) But.. maybe the language allows the developer work out problems differently. With that in mind, perhaps asserting that the language was built for education, [so as to imply that it'll make you a better programmers in general, even in 'bloated or expert' languages], doesn't necessarily shed light on its actual benefits -- but I'll check it out later on to find out for certain.
