In MEL syntax, which construct encapsulates all Mule expressions?

Explanation:
MEL expressions are contained within a #[ ... ] wrapper. This enclosure signals the Mule runtime to evaluate the enclosed content as a Mule Expression Language expression at runtime, allowing you to reference payload, variables, and call functions like #[payload], #[vars.total], or #[now()]. The other forms aren’t MEL expressions: ${ ... } is used for property placeholders from configuration files, not MEL evaluation, and the angle-bracket or parenthetical forms do not denote MEL expressions. So the envelope that encapsulates all Mule expressions is the #[ ... ] wrapper.
