Deprecation Errors instead of Warnings

[akrigline]

Is your feature request related to a problem? Please describe.
It is sometimes difficult to isolate the deprecation warnings from other warnings while testing a module and would be useful to have a "strict" mode which throws errors instead of warnings.

Describe the solution you'd like
I'd like DEBUG mode where deprecation warnings would instead throw errors.

Describe alternatives you've considered
Dealing with deprecations the old fashioned, not easy way.
