I'm +1 on a `-X dev` mode, since it enables a lot of things that are
useful for making an application more robust (extension module
debugging, explicit scope-controlled resource management) that I
wouldn't want turned at the REPL by default. It also implicitly
adjusts over time as we add more debugging capabilities.
I don't consider it a replacement for tweaking how we handle
DeprecationWarning by default, though :)
