>I think that is more a difference in which frameworks you use as opposed to which language.

I don't think it has much to do with which language per se but more to do with what the language community considers acceptable. You can write mostly head-ache free frameworks filled with "magic" in Java like the rest of them, but it's not a strong cultural value.

To turn to the microframeworks example, I can't speak to Spark but in Ruby land it is not hard to flesh out your sinatra app into a more complex beast should the need arise - converting Sinatra half way to a mini Rails is not something I would recommend, but mostly because you lose easy-library support and ease-of-update down the road (you shouldn't be writing your own custom framework period, sort of thing), and not necessarily because of a lack of flexibility.
