When do you ever need dynamism? When do you ever need monkey-patching, eval, heterogeneous collections, and shit like this?

monkey-patching
Almost never.

eval
Almost never.

heterogeneous collections
A lot more often than you think.

and shit like this
I suppose this includes not having to spend time on typing type signatures.
