Get contract address in Solidity
================================
Short answer: The global variable ``this`` is the contract address.
See `basic_info_getter <https://github.com/fivedogit/solidity-baby-steps/blob/master/contracts/15_basic_info_getter.sol>`_.
Long answer: ``this`` is a variable representing the current contract.
Its type is the type of the contract. Since any contract type basically inherits from the
``address`` type, ``this`` is always convertible to ``address`` and in this case contains
its own address.
