New issue 2142 by asmeurer: Turn on deprecation warnings in isympy
http://code.google.com/p/sympy/issues/detail?id=2142
Python 2.7 ignores DeprecationWarning by default (see
http://docs.python.org/library/warnings.html#warning-categories). The idea
I think is that users don't want to be bombarded with deprecation warnings
just because they are using a module or script where someone is using
something deprecated.
But I think we want to have it on in isympy so that people see it when they
use deprecated sympy functionality. The solution is in the -W flag to
Python (see
http://docs.python.org/library/warnings.html#the-warnings-filter). Also,
maybe we should create a SymPyDeprecationWarning and only turn those on.
And we should probably run the tests will all warnings turned on and turned
into exceptions so that we avoid using warned behavior in the tests.
