Was getting confused myself, where it was instruction or instructions, when if the base class was inside or out of dir. Now dirs are plural, and base class is inside.

# actually call it.

# As the call setup is done beforehand (for both simple and cached call), the
|
|
# calling really means mostly jumping to the address. Simple.
