new lemma

merged

new theory of filters and limits; prove LIMSEQ and LIM lemmas using filters

more abstract properties of eventually

new lemmas about eventually; rewrite Lim proofs to use more abstract properties of eventually

generalize at function to class perfect_space

generalize topological notions to class metric_space; add class perfect_space

instance ^ :: (metric_space, finite) metric_space

generalize tendsto and related constants to class metric_space

add lemmas Lim_at_iff_LIM, Lim_sequentially_iff_LIMSEQ

remove duplicate cauchy constant

fix reference to LIM_def

instance * :: (metric_space, metric_space) metric_space; generalize lemmas to class metric_space

generalize constants from Lim.thy to class metric_space

LIMSEQ_def -> LIMSEQ_iff

generalize constants in SEQ.thy to class metric_space

early setup of secure operations (again, cf. deddd77112b7) -- NB: fix_ints is required for bootstrap; late setup of ML_Env and ML_Compiler;

structure ML_Compiler;

added structure ML_Compiler: runtime compilation, with advanced version for Poly/ML 5.3 (formerly ML_Test);

added flatten;

tuned signature;

export secure_mltext;

tuned comments;

maintain tokens within common ML environment;

ML_Env;

slightly later setup of ML and secure operations;

moved local ML environment to separate module ML_Env;

removed print function from global ML name space, to reduce risk of surprises;

made SML/NJ happy;

attempt to eliminate adhoc makestring at runtime (which is not well-defined);

eliminated misleading dummy versions of print/makestring, cf. 6974449ddea9;

provide local dummy version of makestring -- NB: makestring is fragile and not portable, it should not occur in repository sources;

no longer open PolyML -- to avoid surprises within the global name space; recovered some important PolyML bindings (NB: print and makestring cannot be rebound without loosing infinite overloading);

explicit PolyML qualification;

removed "compress" option from isabelle-process and isabelle usedir -- this is always enabled;

test experimental Poly/ML 5.3;

removed obsolete COPYDB flag;

explicit PolyML.install_pp;

renamed polyml_pp.ML to pp_polyml.ML; explicit PolyML.install_pp;

more modular setup of runtime compilation;

more precise version information;

uniform treatment of shellscript mode;

updated example settings;

discontinued support for Poly/ML 4.x versions;

ISABELLE_USEDIR_OPTIONS: proper word splitting of quoted options (via array variable and special expansion, cf. "$@");

eliminated old Attrib.add_attributes (and Attrib.syntax);

modernized attribute setup; removed obsolete no_args, add_del_args;

eliminated old Method.add_method(s);

removed obsolete combinators for method args;

proper signature constraint; modernized method setup;

minimal signature cleanup; modernized method setup;

modernized method setup; tuned;

modernized method setup;

tuned;

tuned;

simps with mandatory name prefix

corrected bound/unbounded flag for nat numerals

removed dead theory Relation_Power

fix reference to dist_def
