def _is_intrinsic_dict(self, input):
<EOL>return isinstance(input, dict)and len(input) == <NUM_LIT:1>and list(input.keys())[<NUM_LIT:0>] in self.supported_intrinsics<EOL>
Can the input represent an intrinsic function in it?

:param input: Object to be checked
:return: True, if the input contains a supported intrinsic function.  False otherwise
