* @brief A synchronous execution context. Runs on the caller thread.

|
|
* This execution context runs the operations on the same thread that requested the operation to run.
|
|
* Each operation must finish before the corresponding `execute` returns an operation object that can immediately be
|
|
* queried for value or error as it's guaranteed to have completed. Timer-based operations are scheduled via
|
|
* SystemExecutionContext, including those that are scheduled from within a strand.
