Objects in UCBLogo

[jasonsikes]

Hello, all!

I am playing around with Logo's new objects. As a mostly C++ and Python user I find Logo's objects to be... different. Not bad! Especially considering the goal is to be easy to understand and still be useful, this design checks all the boxes!

Here are some quirks.

1. There are three things I found that cause segfaults.

A.

? make "name logo
? show logo

B.

? make "a something
? make "b ask :a [parents]
? .setbf :b [hello there]
? ask :a [show parents]

and

C.
? show first self

2. The following are not problems (I believe), but I have questions.

A. Is there a way to remove a variable or procedure from an object?

B. Is HAVEMAKE intended to be a library procedure, similar to LOCALMAKE?

C. What happens if a user makes an object with the same parent listed twice? e.g.

? make "a (kindof self self)

or, similarly:

? make "a something
? ask :a [.setbf parents se logo logo]
? ask :a [show parents]

Thank you guys! This is looking really good!
