But it's recursively interwoven.... If it was nonrecursive things
would be much uglier ;-)
IMHO, to ammend to stevan's mail, one fundamental step is linking.
This happens in the middle of the type checking phase - some type
info is extracted from a single unit, and other type info is
extracted from already compiled units that are being linked.
In Perl 5 linkage was completely ad-hoc, and was imperative, and
side effect reliant, as opposed to declarative:
*{$sym} = $subref;
The reason this part is fundamental is that it implies the
separation between the bits of code.
