> *Note*: A *local_variable_declaration* that includes a *local_variable_initializer* is still initially unassigned. Execution of the declaration behaves exactly like an assignment to the variable ([§9.4.4.5](variables.md#9445-declaration-statements)). It is possible to use a variable without executing its *local_variable_initializer*; e.g., within the initializer expression itself or by using a *goto_statement* to bypass the initialization:

> *Example*: The following example demonstrates definite assignment for captured variables in local functions. If a local function reads a captured variable before writing it, the captured variable must be definitely assigned before calling the local function. The local function `F1` reads `s` without assigning it. It is an error if `F1` is called before `s` is definitely assigned. `F2` assigns `i` before reading it. It may be called before `i` is definitely assigned. Furthermore, `F3` may be called after `F2` because `s2` is definitely assigned in `F2`.
