It felt quite outdated to me. I tried reading it quite a few years ago as a student, but gave up on the books old-fashioned ideas.
The book is very imperative and doesn't really know much about modern abstractions for data structures.
Something like https://en.wikibooks.org/wiki/Write_Yourself_a_Scheme_in_48_... is probably more fun for a beginner these days. (Languages in the ML family are really well suited to writing parsers, interpreters and compilers. That what that family of languages was designed for.)
