* ``.address`` returns the address of the contract of the function.
* ``.selector`` returns the :ref:`ABI function selector <abi_function_selector>`
* ``.gas(uint)`` returns a callable function object which, when called, will send
the specified amount of gas to the target function. Deprecated - use ``{gas: ...}`` instead.
See :ref:`External Function Calls <external-function-calls>` for more information.
* ``.value(uint)`` returns a callable function object which, when called, will
send the specified amount of wei to the target function. Deprecated - use ``{value: ...}`` instead.
See :ref:`External Function Calls <external-function-calls>` for more information.
.. note::
External (or public) functions used to have the additional members
``.gas(uint)`` and ``.value(uint)``. These were deprecated in Solidity 0.6.2
and removed in Solidity 0.7.0. Instead use ``{gas: ...}`` and ``{value: ...}``
to specify the amount of gas or the amount of wei sent to a function,
respectively. See :ref:`External Function Calls <external-function-calls>` for
more information.
Example that shows how to use the members::
pragma solidity >=0.6.0 <0.8.0;
// This will report a warning
pragma solidity >=0.6.4 <0.8.0;
