Conversions: Conversions:
A value of external function type can be explicitly converted to ``address``
resulting in the address of the contract of the function.
A function type ``A`` is implicitly convertible to a function type ``B`` if and only if A function type ``A`` is implicitly convertible to a function type ``B`` if and only if
