[Bug]: No error given for illegal cyclic reference

[rdulmina]

Description

illegal cyclic reference not given for the following sample

function() returns boolean a = function() returns boolean {
    return b;
};

boolean b = a();

The following sample gives the error as expected

function a() returns boolean {
    return b;
};

boolean b = a();

To be consistent, the first sample should also give an error
