|
|
* Region pointers and borrow checking supersede alias
|
|
analysis
|
|
* Init-ness checking is now provided by a region-based liveness
|

pass instead of the typestate pass; same for last-use analysis
|
|
* Extensive work on region pointers
|
|
|
|
* Experimental new language features
|
|
* Slices and fixed-size, interior-allocated vectors
|
|
* #!-comments for lang versioning, shell execution
|
|
* Destructors and iface implementation for classes;
|
|
type-parameterized classes and class methods
|

|
|
shared-memory concurrency patterns
|
|
|
|
* Type reflection
|
|
|
|
* Removal of various obsolete features
|
|
* Keywords: 'be', 'prove', 'syntax', 'note', 'mutable', 'bind',
|
|
'crust', 'native' (now 'extern'), 'cont' (now 'again')
|
|
|
|
* Constructs: do-while loops ('do' repurposed), fn binding,
|
|
resources (replaced by destructors)
|
|
|
|
* Compiler reorganization

|
* Extensive work on libuv interface
|
|
* Much vector code moved to libraries
|
|
* Syntax extensions: #line, #col, #file, #mod, #stringify,
|
|
#include, #include_str, #include_bin
|
|
|
|
* Tool improvements

Version 0.1 (January 2012)
|
|
---------------------------
|
|
|
|
* Most language features work, including:
|
|
* Unique pointers, unique closures, move semantics
|
|
* Interface-constrained generics
|
|
* Static interface dispatch
|
|
* Stack growth
|
|
* Multithread task scheduling
|
|
* Typestate predicates
|
|
* Failure unwinding, destructors
|
|
* Pattern matching and destructuring assignment
|
|
* Lightweight block-lambda syntax
|
|
* Preliminary macro-by-example
|
|
|
|
* Compiler works with the following configurations:
|
|
* Linux: x86 and x86_64 hosts and targets
|
|
* MacOS: x86 and x86_64 hosts and targets
|
|
* Windows: x86 hosts and targets
|
|
|
|
* Cross compilation / multi-target configuration supported.
|
|
|
|
* Preliminary API-documentation and package-management tools included.
|
|
|
|
Known issues:
|
|
|
|
* Documentation is incomplete.
|
|
|
|
* Performance is below intended target.
|
|
|
|
* Standard library APIs are subject to extensive change, reorganization.
|
|
|
|
* Language-level versioning is not yet operational - future code will
|
|
break unexpectedly.
