+//
+//	obj may be a callable, class, or module.
+//	Passing in an object of any other type raises TypeError.
+//
+//	Returns a dict.  get_annotations() returns a new dict every time
+//	it's called; calling it twice on the same object will return two
+//	different but equivalent dicts.
+//
+//	This function handles several details for you:
+//
+//	  * If eval_str is true, values of type str will
+//	    be un-stringized using eval().  This is intended
+//	    for use with stringized annotations
+//	    ("from __future__ import annotations").
+//	  * If obj doesn't have an annotations dict, returns an
+//	    empty dict.  (Functions and methods always have an
+//	    annotations dict; classes, modules, and other types of
+//	    callables may not.)
+//	  * Ignores inherited annotations on classes.  If a class
+//	    doesn't have its own annotations dict, returns an empty dict.
+//	  * All accesses to object members and dict values are done
+//	    using getattr() and dict.get() for safety.
+//	  * Always, always, always returns a freshly-created dict.
+//
+//	eval_str controls whether or not values of type str are replaced
+//	with the result of calling eval() on those values:
+//
+//	  * If eval_str is true, eval() is called on values of type str.
+//	  * If eval_str is false (the default), values of type str are unchanged.
+//
+//	globals and locals are passed in to eval(); see the documentation
+//	for eval() for more information.  If either globals or locals is
+//	None, this function may replace that value with a context-specific
+//	default, contingent on type(obj):
+//
+//	  * If obj is a module, globals defaults to obj.__dict__.
+//	  * If obj is a class, globals defaults to
+//	    sys.modules[obj.__module__].__dict__ and locals
+//	    defaults to the obj class namespace.
+//	  * If obj is a callable, globals defaults to obj.__globals__,
+//	    although if obj is a wrapped function (using
+//	    functools.update_wrapper()) it is first unwrapped.
