* first implementation of the =trace and =dispose hooks for the cycle collector
* a cycle collector for ARC: progress
* manual: the .acyclic pragma is a thing once again
* gcbench: adaptations for --gc:arc
* enable valgrind tests for the strutils tests
* testament: better valgrind support
* ARC refactoring: growable jumpstacks
* ARC cycle detector: non-recursive algorithm
* moved and renamed core/ files back to system/
* refactoring: --gc:arc vs --gc:orc since 'orc' is even more experimental and we want to ship --gc:arc soonish
* cursors: first implementation
* added currently failing test
* .cursor works for doubly linked lists
* make -d:useMalloc work again
* added code to nil out refs in a destructor
* it's now called --gc:arc
* renderer.nim: render nkBreakState properly
* make simple closure iterators work without leaking
This is more friendly to those browsing the documentation without
a network connection. The nim-doc package in Debian allows this,
for example.
Also, the domain name being used was not consistent. It could have
been either nim-lang.org or nim-lang.github.io, and those reading
the stable docs could have found themselves suddenly reading the
devel docs instead.
* Locks modules should give a compile error when threads are not enabled.
* fix the compile flags to make the tests pass, or ignore files where necessary.
* Fixed when statement to account for doc builds.
* new .gensym implementation
* make astspec test green again
* introduce a --useVersion switch to group compatibility switches
* fixes#10180
* fixes#11494
* fixes#11483
* object constructor fields and named parameters are also not gensym'ed
* disabled broken package
Fixes:
> macros.nim(1423, 35) Warning: `typed` will change its meaning in future versions of
Nim. `void` or no return type declaration at all has the same
meaning as the current meaning of `typed` as return type declaration. [Deprecated]
