Definitions:

• callable: something that can be called with params; like a function, method, procedure, macro...
• Point:: 2d tuple/list/array or object/struct with coordinates (x, y) as attributes/fields
• Region: a callable that receive a point and return true if is inside of a a region, and false if is out.
• Distance : a float

Problem:

• We have a two tanks (in a two positions), and we want to know if we can shot to another positions without danger.
• The tanks have a secure region defined by a circle
• The tanks have a maximun shot distance.
