### Kernel module
|
|
|
|
|
|
|
|
|
|
As of writing Kernel is an "old style" module, aka a bunch of functions.
|
|
|
|
|
|
|
|
|
|
These functions return their code, ie a Vm::Function object, which can then be called by ruby code as if it were a "normal"
|
|
|
|
|
function.
|
|
|
|
|
|
|
|
|
|
A normal ruby function is one that is parsed and transformed to code. But not all functionality can be written in ruby,
|
|
|
|
|
one of those chicken and egg things. C uses Assembler in this situation, we use Kernel function.

The Kernal module is scattered into several files, but that is just so the file doesn't get too long.

PS: Old style also means the acual receiver is not used. Kernel function are more like global functions.
|
|
|
|
|
PPS: New style is what rails pioneered and has now called Concerns. I call them Aspects, and they not only serve to split
|
|
|
|
|
a big file up, but use the receiver and also super, ie the fact that a module gets inserted into the method lookup
|
|
|
|
|
sequence in just the same way as an superclass. This solves the old c++ and Java multiple inheritance dilemma.
