2010-09-01 ago replaced Table.map' by Table.map
2010-06-02 ago always unconstrain thm proofs;
2010-06-02 ago normalize and postprocess proof body in a separate future, taking care of platforms without multithreading (greately improves parallelization in general without the overhead of promised proofs, cf. usedir -q 0);
2010-06-01 ago merged
2010-06-01 ago - outer_constraints with original variable names, to ensure that argsP is consistent with args
2010-05-31 ago modernized some structure names, keeping a few legacy aliases;
2010-05-14 ago added Proofterm.unconstrain_thm_proof for Thm.unconstrainT -- loosely based on the version by krauss/schropp;
2010-05-13 ago conditionally unconstrain thm proofs -- loosely based on the version by krauss/schropp;
2010-05-13 ago avoid redundant rebinding of name/prop -- probably introduced accidentally in 80bb72a0f577;
2010-05-13 ago raise Fail uniformly for proofterm errors, which appear to be rather low-level;

2010-05-08 ago back-patching of axclass proofs;
2010-05-07 ago strip_shyps_proof: dummy TFrees are called "'dummy" as in del_conflicting_tvars below;
2010-05-04 ago proof terms for strip_shyps, based on the version by krauss/schropp with some notable differences:
2010-05-04 ago simplified/unified fundamental operations on types/terms/proofterms -- prefer Same.operation over "option" variant;
2010-05-04 ago renamed Proofterm.freezeT to Proofterm.legacy_freezeT (cf. 88756a5a92fc);
2010-03-21 ago do not open ML structures;
2010-03-20 ago renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;

2009-11-25 ago normalized uncurry take/drop
2009-11-24 ago curried take/drop
2009-11-16 ago generalized procs for rewrite_proof: allow skeleton;
2009-11-08 ago adapted Theory_Data;
2009-11-05 ago revert fulfill_proof_future tuning (actually a bit slower due to granularity issues?);
2009-11-04 ago fulfill_proof_future: tuned important special case of singleton promise;

2009-10-21 ago curried union as canonical list operation
2009-10-21 ago dropped redundant gen_ prefix
2009-10-20 ago replaced old_style infixes eq_set, subset, union, inter and variants by generic versions
2009-10-01 ago back to simple fold_body_thms and fulfill_proof/thm_proof (reverting a900d3cd47cc) -- the cycle check is implicit in the future computation of join_proofs;
2009-09-30 ago eliminated redundant parameters;
2009-09-29 ago explicit indication of Unsynchronized.ref;
2009-09-28 ago fold_body_thms: pass pthm identifier;
2009-09-27 ago fold_body_thms/join_bodies: explicitly check for cyclic theorem references;
2009-07-24 ago get_name: cover only PThm, not PAxm;
2009-07-21 ago prefer simultaneous join -- for improved scheduling;
2009-07-19 ago tuned;
2009-07-18 ago added join_bodies;

2009-07-02 ago added pro-forma proof constructor Inclass;
2009-03-25 ago removed misleading make_proof_body, make_oracles, make_thms, which essentially assume a *full* proof;
2009-03-24 ago status_of: simultaneous list;
2009-03-24 ago display derivation status of thms;
2009-02-27 ago eliminated NJ's List.nth;
2009-01-27 ago thm_proof: recovered single-threaded version;
2009-01-27 ago thm_proof: replaced lazy by composed futures;
2009-01-27 ago proof_body: turned lazy into future -- ensures that body is fulfilled eventually, without explicit force;
