"""
By default non-serializable objects are going through
safe_repr(). For certain places in the event (local vars) we
want to repr() even things that are JSON-serializable to
make their type more apparent. For example, it's useful to
see the difference between a unicode-string and a bytestring
when viewing a stacktrace.
For container-types we still don't do anything different.
Generally we just try to make the Sentry UI present exactly
what a pretty-printed repr would look like.
:returns: `True` if we are somewhere in frame variables, and `False` if
we are in a position where we will never encounter frame variables
when recursing (for example, we're in `event.extra`). `None` if we
are not (yet) in frame variables, but might encounter them when
recursing (e.g. we're in `event.exception`)
