Why is enum class preferred over plain enum?
... workmate adds carelessly a new value to our enum:
E_DEVIL_FRUIT = 0x100, // New fruit, with value greater than 8bits
The compiler doesn't complain about it! It just resizes the type to fit all the values of the enum (assuming that the compiler were using the smallest type possible, which is...
Is there a way to detect if a browser window is not currently active?

Live example of that here.
Old posterity answer:
There's nothing native that allows you to natively use SVG paths in canvas. You must convert yourself or use a library to do it fo...
List comprehension rebinds names even after scope of comprehension. Is this right?
...expression. The less insane way found was single-value for clauses eg. sum100 = [s for s in [0] for i in range(1, 101) for s in [s + i]][-1], but just needs a comprehension-local var and works just as well in Python 3. I think "leaking" was the only way to set variable visible outside an expressio...
