The semantics of assignment are a bit more complicated for non-value types like arrays and structs.
Assigning *to* a state variable always creates an independent copy. On the other hand, assigning to a local variable creates an independent copy only for elementary types, i.e. static types that fit into 32 bytes. If structs or arrays (including ``bytes`` and ``string``) are assigned from a state variable to a local variable, the local variable holds a reference to the original state variable. A second assignment to the local variable does not modify the state but only changes the reference. Assignments to members (or elements) of the local variable *do* change the state.

Scoping and Declarations
========================
-.. index:: ! scoping, ! declarations, ! default-value
-
In Solidity, a variable which is declared is automatically assigned its default value. It will be assigned on contract
initialization if it is a contract-level variable or at the beginning of a function call if it is a local variable.
This is because the EVM must run deterministically so it would be inappropriate to initialize any variables to random garbage values.
