Here's the abstract:

>Interactive REPL-driven systems (that most Schemes are) need a way to get detailed information on a given piece of data. Inspectors, as these are conventionally called. This SRFI defines a basic protocol for inspectors, consisting of two procedures: inspect-properties and inspect-describe. Some suggestions for standard and popular types' inspection are also provided.

Here are Wolfgang's comments for finalization:

>There a couple of outstanding commits that I'd like to merge before finalizing:

>https://github.com/scheme-requests-for-implementation/srfi-271/pull/6

>These are (critical!) sample implementation fixes.  Only e5bd7323 changes the SRFI doc; it adds a small pointer to SRFI 277, which was suggested by Peter McGoron.  I don't think this warrants another draft.

Here is the commit summary since the most recent draft:

• Implementation: Fix bad bug in xoshiro256++ code.
• Use macros for accessors instead of procs.
• Implementation: Use open-binary-input-file.
• Implementation note.
• Add See-also link to SRFI 277.
• Add short paragraph about SRFI 277.
• copy edits
• Update table of contents.
• Finalize.

Here's the abstract:

>This SRFI follows the traditional Scheme model of pretty printing, which treats it as a process distinct from general controlled formatting. While general-purpose formatters often prioritize specialized presentation at the expense of machine-readability, Scheme’s pretty-printers (such as those of SLIB and MIT Scheme) have traditionally treated pretty printing as a variant of write, differing primarily in the insertion of whitespace to make the presentation more palatable to humans. Common Lisp’s pretty-printer, by contrast, fills two roles simultaneously by integrating pretty printing with both its format facility and its generalized write procedures. This unified approach offers great power, but at the cost of complexity that can make it difficult to use effectively. We propose a specialized, layered approach, specifying five libraries of increasing functionality, where all but the first are optional. The libraries are downward-compatible: more powerful libraries satisfy all requirements of the simpler ones while adding new features. Implementors may choose to support a maximum level of functionality appropriate for their systems. Integration with monadic and string-based formatting libraries is supported.
