There were significant overlaps in the names of data structures
between the compiler and the language that made it necessary

requirement in most places (Parser is ambiguous wherever TreeSitter
is used -- cannot avoid that!)

resolve those to absolute path names.

The compilation code was written as a precursor for implementation
with macros. The updates in this commit make the switch.
There is still plenty to do:
1. Comment Walker.
2. Comment Macros.

Add support functions to check whether a (block of) statement(s) contains
any statements that should not appear in that block (e.g., switch in
an action).
