+/**
+ * This file adds a 'guardedCatch' function to the Promise API. This function
+ * has to be used when we don't want to swallow real errors (crashes), like
+ * 'catch' does (i.e. basically all the time in Odoo). We only execute the
+ * 'onRejected' handler if the rejection's reason is not an Error, and we always
+ * return a rejected Promise to let the rejection bubble up (and trigger the
+ * 'unhandledrejection' event).
