 * `fn` {Function} Function to wrap a trace around
 * `context` {Object} Shared object to correlate trace events through
 * `thisArg` {any} The receiver to be used for the function call
 * `...args` {any} Optional arguments to pass to the function
-* Returns: {any} The return value of the given function, or the result of
-  calling `.then(...)` on the return value if the tracing channel has active
