I would strongly recommend not.

That doesn't work in a function, but outside of a function, you should
be able to use:

globals().update(dictionary)

However, I would advise using the dictionary explicitly. Give it a
shorter name and it'll be easier, but don't go for namespace
pollution. The PHP folks finally realized that register_globals is a
bad idea.
