10 * FIXME |
10 * Explicit proof terms for type class reasoning. |
11 |
11 |
|
12 * Authentic syntax for *all* logical entities (type classes, type |
|
13 constructors, term constants): provides simple and robust |
|
14 correspondence between formal entities and concrete syntax. |
|
15 |
|
16 * HOL: Package for constructing quotient types. |
|
17 |
|
18 * HOL: Code generation now with simple concept for abstract |
|
19 datatypes obeying invariants; applications for typical data structures |
|
20 (e.g. search trees) can be found in the library. |
|
21 |
|
22 * HOL: New development of the Reals using Cauchy Sequences. |
|
23 |
|
24 * HOL: Reorganization of abstract algebra type class hierarchy. |
|
25 |
|
26 * Commands 'types', 'typedecl' and 'typedef' now work within a local theory |
|
27 context -- without introducing dependencies on parameters or |
|
28 assumptions. |
