I'm learning ruby on rails on a linux box and dusting off my VIM skills (skillz?). When I got started on VIM way back in my c++ days, I had a friend with a great vimfiles folder that had tons of stuff to get started. Starting from scratch, vim is great, but it feels like it could be a lot better. I currently have: vim-ruby buffer ...
Q: The title is perhaps too big of question and the answer probably is "it depends"? However, providing some practical cases/examples should help developers, like myself, recognize when to apply what. I'll start out with my particular situation.

Is there any way to feather an image from code?

I don't have much experience with statically typed languages (currently learning Scala and loving it!) but one thing I've noticed is that they don't ever seem to have anything like Ruby's method_missing or ColdFusion's onMissingMethod. Is there some inherent limitation in statically typed languages that prevent or make this difficult? ...
