Inconsistent Syntax for Unit Test Attributes in Codebase

Now, our unit tests are objects, while in reality they are not. How about we introduce a new syntax for test "attributes":

```
[n] > fibo
  if. > @
    n.lt 2
    1
    plus.
      fibo (n.minus 1)
      fibo (n.minus 2)

  eq. +> fibo-5th-equals-to-seven
    7
    fibo 5
```
