Features
|
|
|
|
- Added a `(scheme cyclone match)` library based on Alex Shinn's `match.scm` portable hygienic pattern matcher.
|
|
- The compiler now emits a faster version of `apply` in cases where only two arguments are received.
|
|
|
|
Bug Fixes
|
|
|
|
- Made several improvements to macro hygiene by renaming local variable bindings during expansion. Added a unit test module covering many test cases.
|
|
- Fixed many functions including `utf8->string`, `string->utf8`, `bytevector-copy`, `list->vector`, and `list->string` to heap allocate objects that exceed the maximum size for objects on the stack.
|
|
- Prevent a compiler error when there is only one argument to `+` or `*`.
