 Functions can be declared ``pure`` in which case they promise not to read from or modify the state.

 #. Reading from state variables.
 #. Accessing ``this.balance`` or ``<address>.balance``.
 #. Accessing any of the members of ``block``, ``tx``, ``msg`` (with the exception of ``msg.sig`` and ``msg.data``).
