# metaclasses

This example illustrates how to work with metaclasses in Logtalk.
See also the `reflection` and `roots` examples for a followup on
using metaclasses.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

```logtalk
%versions
```

Start by loading the example:

```logtalk
logtalk_load(metaclasses(loader)).
```

Play and modify the example code to get comfortable using classes and
instances in Logtalk.

```logtalk
root::new(I).
```

<!--
Instance created.
I = o1.
-->

```logtalk
subclass1::new(I).
```

<!--
Instance created.
Instance initialized.
I = o2.
-->

```logtalk
subclass2::new(I).
```

<!--
I = o3.
-->
