* Exception handling. Functionality is similar to C++ try/catch.
* Usage example:
Trap trap;
if (set_trap(&trap)) {
// Some code that can throw an exception by calling exception()
...
clear_trap(&trap);
}
else {
// Exception handling code
if (trap.error == ...
...
}
* Only main thread is allowed to use exceptions.
