Writing a parser

Today I learned the basics of how to write a parser:

• https://lisperator.net/pltut/parser/input-stream
• https://lisperator.net/pltut/parser/token-stream
• https://lisperator.net/pltut/parser/the-ast
• https://lisperator.net/pltut/parser/the-parser

I don’t yet get all the patterns and the code seems a bit clunky. The error reporting is all over the place, too. But the test cases pass 😂

Emitting the garbage separately

I got this idea from here:

Somehow I like the concept that the parser only returns groups, and they are not tainted with garbage. If I want to know about the garbage, I need to provide a separate observer during the parsing process.
