/// @assertion An unqualified function invocation i has the form
/// id(a1, ..., an, xn+1: an+1, ..., xn+k: an+k), where id is an identifier.
/// If there exists a lexically visible declaration named id, let fid be the
/// innermost such declaration. Then:
/// . . .
///  • If fid is a local function, a library function, a library or static getter
///    or a variable then i is interpreted as a function expression invocation.

/// @description Checks that if fid is a local variable declaration,
/// then i is interpreted as a function expression invocation.
