How expensive is RTTI?
...GCC uses negligible space and typeid(a) == typeid(b) is very fast, on many platforms (Linux, BSD and maybe embedded platforms, but not mingw32). If you know you'll always be on a blessed platform, RTTI is very close to free.
Gritty details:
GCC prefers to use a particular "vendor-neutral" C++ ABI[...

There's a lot of chatter about this not being "platform independent", but when you're using an api that's made for a specific platform, who cares about portability. Checking for equality on the same platform will never fail. These enum'd values are easier to read and th...
Clear terminal in Python [duplicate]
...
A simple and cross-platform solution would be to use either the cls command on Windows, or clear on Unix systems. Used with os.system, this makes a nice one-liner:
import os
