Released Cyclone Scheme 0.35.0

August 25th, 2022

Features

• Arthur Maciel added make-opaque to (cyclone foreign).
• Add memory-streams to the list of symbols that (features) can return, indicating that the current installation supports in-memory streams.

Bug Fixes

• Prevent an error when evaluating a begin expression that contains both a macro definition and an application of that macro. For example:

  begin (define-syntax foo (syntax-rules () ((foo) 123))) (foo))
  

• Fix a regression where c-compiler-options was not recognized as a top level form by programs.
• Enforce a maximum recursion depth when printing an object via display or write, and when comparing objects via equal?. This prevents segmentation faults when working with circular data structures.
• Added proper implementations of assv and memv. Both were previously implemented in terms of assq and memq, respectively.
