Released Cyclone Scheme 0.11.3

August 14th, 2019

Features

• Arthur Maciel added instructions for building Cyclone on FreeBSD.
• Added support for delays and promises to (cyclone concurrent). Note functions/macros for both types of objects are prefixed with shared- to differentiate them from R7RS definitions from (scheme lazy).
• Added platform (linux, bsd, etc) to the list of emitted by (features) and to the features recognized by cond-expand.
• Optimize compilation of vector for five arguments or less, and compilation of map / for-each with two list arguments.

Bug Fixes

• Fixed the MSYS2 build script and instructions, so it is possible to build on Windows again!
• Modified (srfi 27) to use the timer to seed the pseudorandom number generator.
• Fixed exit to return the appropriate status code when a boolean is passed, per R7RS:

  If no argument is supplied, or if obj is #t, the exit procedure should communicate to the operating system that the program exited normally. If obj is #f, the exit procedure should communicate to the operating system that the program exited abnormally.

• Enhanced the interpreter (eval) to properly support splicing in definitions introduced by begin.
• Fixed define-record-type so now it works in the interpreter.
