This functionality, ie getting the n'th data in an object, is essential, but c makes such a good point of of it having no place in a public api. So it needs to be implemented in a "private" part and used in a save manner. More on the layers emerging below.

The Kernel functions return function objects. Kernel functions have the same name as the function they implement, so Kernel::putstring defines a function called putstring. Function objects (Vm::Function) carry entry/exit/body code, receiver/return/argurmt types and a little more.

The important thing is that these functions are callable from ruby code. Thus they form the glue from the next layer up, which is coded in ruby, to the machine layer. In a way the Kernel "exports" the machine functionality to crystal.

I just want to mention the idea of extensions that is a logical step for a minimal system. Off course they would be gems, but the integesting thing is they (like sapphire) could:
|

|

- use crystals existing kernel/machine abstraction to define new functionality that is not possible in ruby
|

- use sapphires existing kernel/machine abstraction to define new functionality that is not possible in ruby
|
||||
- define new machine functionality, adding kernel type api's, to create wholly new, possibly hardware specific functionality

I am thinking graphic accellaration, GPU usage, vector api's, that kind of thing. In fact i aim to implement the whole floating point functionality as an extensions (as it clearly not essential for OO).
