handle Pattern.MATCH, not arbitrary exceptions; misc tuning, trying to reduce line length a bit;

more precise dependencies;

eliminated redundant parameters;

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;

avoid mixed l/r infixes, which do not work in some versions of SML;

tuned;

merged

explicitly Unsynchronized

Merged.

Propagation of mixins for interpretation; reactivated diagnostic command print_interps.

Archive registrations by external view.

Stricter test: raise error if registration generates duplicate theorem.

Explicit management of registration mixins.

Improved comments and api names.

eliminated dead code, redundant bindings and parameters; use === term operator, which is defined here; handle Type.TYPE_MATCH, not arbitrary exceptions; misc tuning and simplification;

misc tuning and simplification; be explicit about expressions involving infixes with non-obvious priorities; removed dead code; some attempts to recover basic Isabelle coding conventions;

eliminated dead code; eliminated redundant bindings; misc tuning;

eliminated dead code;

Sorts.of_sort_derivation: no pp here;

eliminated redundant bindings; schedule_tasks/require_thy: eliminated obsolete tasks_len, which was a leftover from theory-only parallelization;

actually perform Isar_Document.init on startup;

eliminated dead code; eliminated redundant parameters;

removed dead code; Sorts.of_sort_derivation: removed unused pp;

handle Type.TYPE_MATCH, not arbitrary exceptions;

removed redundant Sign.certify_prop, use Sign.cert_prop instead; tuned;

PARALLEL_GOALS: proper scope for exception FAILED, with dummy argument to prevent its interpretation as variable;

actually export unit parser;

eliminated dead code;

eliminated redundant parameters;
