The only appearance of semicolon in Python's formal grammar is here:
simple_stmt: small_stmt (';' small_stmt)* [';'] NEWLINE
So it's neither purely terminator nor purely separator -- but can be used as
either, or left out entirely if (as is almost always the best idea) you
never stuff more than one stmt on a physical line.
Note, however, that adjacent semicolons are not allowed!
SyntaxError: invalid syntax
So there is no sense in which a trailing semicolon implies a "null stmt", or
other similar fiction. The only null stmt in Python is the explicit "pass".
