Since the macro AST is built as a custom tokenizer inside the system, it needs access to the import set. On the other hand, import sets aren't available until after parsing. Need a way to place this order in a lexer without restricting the expression value of the lexer.
The daft option of accepting import resolution queries at runtime is available but consider better options.
alternate extension mechanism
The STD system will have a lot of traffic for trivial operations like algebra, stream IO will likely not be fast enough. A faster system is in order.
Ideally, it should reuse orchid-extension for message routing and decoding.
orchid-host accepts extensions as impl ExtensionPort
Preprocessor extension
The macro system will not be privileged, it can take control from the interpreter via a custom top-level "let" line type.
Must actually write macro system as recorded in note
Check if any of this needs interpreter, if so, start with that
