/**
 * @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.
 * . . .
 *  • Otherwise, fid is necessarily an instance method or getter of the
 *    enclosing class C, and i is equivalent to the ordinary method invocation
 *    this.id(a1, ..., an, xn+1: an+1, ..., xn+k: an+k).
 * . . .
 * @description Checks that an unqualified invocation is resolved correctly and
 * the innermost matching declaration is used.
