// When exceptions happen in a sub-call, they “bubble up” (i.e. exceptions are rethrown) automatically. 
// Exceptions to this rule are send and the low-level functions call, delegatecall and staticcall – 
// those return false as their first return value in case of an exception instead of “bubbling up”.
