Statement syntax as determined by punctuation is very important in
programming languages. The list of rows in the for statement is
terminated by a colon ":". The restriction applies to intermediate statements.
The last statement in the sequence is
terminated by a semi-colon ";". That is, the row restriction imposed by the for
statment applies to all statements until a statement with a semi-colon
is detected. The range of application is called the "scope" of the
statement.
