"""An expression statement, that is, an expression terminated by a semicolon.
Only certain expressions are valid statements:
- [[assignment|AssignmentOperation]] (but see below),
- [[prefix|PrefixOperation]] or [[postfix|PostfixOperation]] increment or decrement, and
- [[invocation|Invocation]] (or instantiation).
Be aware that very simple assignments are [[specifications|Specification]];
an [[AssignmentStatement]] where the [[target|AssignOperation.target]] of the [[AssignOperation]]
is a [[BaseExpression]] is invalid.
Examples:
text.length += added.length;
i++;
print("Hello, World!");"""
