commit 6c5d9ae0b4c0ebc2422286af048dd2e10aba1ab4
Author: Dridi Boukelmoune <dridi.boukelmoune at gmail.com>
Date: Fri Jun 5 07:44:19 2020 +0200
Split the monolithic VCL symbol table
This introduces two namespaces MAIN and TYPE to allow top-level symbol
collisions for type methods.
For example, `backend` is a reserved keyword but `backend.resolve` is a
type method. It is impossible to declare such a method symbol because it
would require its parent `backend` symbol to be a type symbol.
There would be a conflict between two `backend` symbols of different
kinds. The same would apply if the BLOB type had methods and vmod_blob
was imported.
At this point only the MAIN namespace is used but the split enables the
symbolization of types and type methods down the line.
