I've just published draft #2 of SRFI 224. It was submitted by Wolfgang Corcoran-Mathe, author of the SRFI.

Here are Wolfgang's comments on the draft:

The only significant change to the SRFI is the redefinition of imapping-ref, which now follows the SRFI 146 model.

Here is the commit summary:

• Fix typo.
• Note PD status of pmatch; link original code.
• imapping-unfold: Update multiple-value notation.
• Fix "or #f" error in internal proc. trie-assoc, update users.
• Reorganize and rename implementation files.
• Rename library: integer-map -> (srfi 224).
• Test that imapping-lookup handles #f values correctly.
• Tests: Fix comparison of Maybe values.
• imapping-update: Returns the imapping if k is not found.
• Simplify example.
• Re-specify imapping-ref to take optional continuations.
• Rename internal procedures.
• SRFI 78 tests: Add missing import.
• Tests: Use test-eqv to compare atomic values.
• stop? can return any truthy value.
• Put -ref procedures before -lookup.
• Additional ACKs.
• Publish second draft.
