Depending on the definition you take

I'd say according to perlglossary it must be parsable without surrounding do {}

  • expression

    Anything you can legally say in a spot where a value is required. Typically composed of literals, variables, operators, functions, and subroutine calls, not necessarily in that order.

    • But according to WP expression, the defining characteristic is returning a value

    An expression in a programming language is a combination of one or more constants, variables, operators, and functions that the programming language interprets (according to its particular rules of precedence and of association) and computes to produce ("to return", in a stateful environment) another value.

    I'd compromise on "statement which can be used like an expression to produce values".
