Because they are a kind of rebol dialect. They are blocks with special
meaning.

special things that happen in a function that are all about binding params
and locals, but I would be surprised if functions worked internally like the
dialect that is in parse or view. If it works that way, it's a sheer
revelation to me. In fact, how could you define a dialect without referring
to other functions? Is that a chicken and egg kind of thing?

The:
make function!
that appears in the source for 'func and 'function is where any dialect
pre-processing occurs, and MyFunc is where the function dialect gets
executed. This is where the "magic" happens. 'Func, 'function and 'does are
simply built on top of these.
I hope that helps!
