Comparing const array of classes gives compile error

[Zevenberge]

Referencing fluent-asserts 0.12.2:

import fluent.asserts;

class A{}

unittest
{
    A a = new A();
    const(A)[] arr = [a];
    arr.should.equal([a]); 
}   

fails with compiler error

/usr/include/dmd/druntime/import/object.d(4235,5): Error: static assert:  "Cannot implicitly convert type A to immutable in idup."

If I replace A with a struct (and don't new it), the assert works. This test compiled with fluent-asserts 0.5.0 (and a full-fledged version passed in my project). If required, I can do some more advanced digging to find the exact version in which this regression was introduced.

@Zevenberge thre is no need to do further digging... I will try to fix this during the weekend, but I will not promise :)

It should be fixed now. There is a new release, you should be able to use it. :)

Awesome, thanks :)
