Well, that's from the Objective C history; and Objective C borrows a lot from those languages.

The thing is, once you're doing systems programming, it's unlikely you're going to call any Objective C APIs, or APIs that have an Objective C history. You're more likely to call something in C.

NeXTSTEP systems programming was done in Objective-C, including writing drivers.

Also Objective-C has nothing to do with those languages, so I got lost in what history.

It picks from C and Smalltalk.
