The delete operator in JS is unfortunately an unreliable creature. i
have seen, e.g.:

var x = new QWidget();
...
delete x;
print(x); // "QWidget", or similar

IMO print(x) should print "null". i don't know if this is JS behaviour
in general or specific to the QtScript engine, however.

Another thing i have seen when running scripts from inside an app:

var x = new QWidget();
...
x.deleteLater();
...

The native func will not be deleted until deleteLater() is safe (after
the event queue finished, if i'm not mistaken). If you run the JS
script in response to some event (e.g. double-click in my case) no
objects destroyed that way will be destroyed until after the script is
finished. e.g. i have a game in which i'd like to create and destroy
pieces from script. i can create them fine, but when i destroy them
they don't actually go away until the script is finished (which isn't
terribly helpful in some cases).

Anyway... just a small tip.
