Language and System Features
New Features:
- User-defined types are now available for the first time.
This facility allows the user to declare new type names and create
objects with such types and then supply some basic primitives and
intrinsic functions for such objects.
Changes and Removals:
- When SetQuitOnError(true) is in force, the exit status is now
non-zero when Magma exits due to an error.
Bug Fixes:
- Fixed a possible crash when a syntax error arises within a function
definition.
- Fixed a crash that could arise when using eval with a
database around.
- The algorithm deciding the frequency of garbage collection has been revised
so as to spend much less time in some situations.
