x = Point(1,2)
It is important to use the self parameter ...

How to implement a binary tree?
...ge anything. My guess is that Fox is simply used to coding a language like C++ or Java, which require the semicolon at the end of the line. Aside from that optional use, semicolons can be used to chain statements in a single line. For example a=1; b=2; c=3 would be a valid single line in python.
