Jak je zn\u00e1mo, programovac\u00ed jazyk C++ je pravd\u011bpodobn\u011b nejrozs\u00e1hlej\u0161\u00ed z jazyk\u016f. Dokonce i program\u00e1to\u0159i, kte\u0159\u00ed na n\u011bm p\u00ed\u0161\u00ed des\u00edtky let, se nemohou pochlubit t\u00edm, \u017ee ho znaj\u00ed dokonale. V souvislosti s t\u00edm p\u0159ijala standardiza\u010dn\u00ed komise C++ nelehk\u00fd \u00fakol: aby jazyk z\u016fstal konkurenceschopn\u00fd v\u016f\u010di nov\u00fdm jazyk\u016fm, jako je Rust, je t\u0159eba odstranit v\u0161echny legacy funkce, kter\u00e9 byly naps\u00e1ny nezn\u00e1m\u00fdmi \u201egobliny\u201c v hu\u0148at\u00fdch osmdes\u00e1t\u00fdch letech. V tom pomohou dob\u0159e zn\u00e1m\u00ed v\u00fdvoj\u00e1\u0159i Gnome, kte\u0159\u00ed kdysi odstranili v\u0161echny nadbyte\u010dn\u00e9 funkce ze sv\u00e9ho desktopov\u00e9ho prost\u0159ed\u00ed, \u010d\u00edm\u017e ho u\u010dinili bezkonkuren\u010dn\u00edm. Budou odstra\u0148ovat v\u0161echny funkce, dokud nezmiz\u00ed v\u0161echny \u201eplusy\u201c a nedostanou se k C, ze kter\u00e9ho C++ vlastn\u011b vze\u0161lo, ale t\u00edm se nezastav\u00ed a ponechaj\u00ed z jazyka pouze minim\u00e1ln\u00ed C.<\/p>\n
A to konkr\u00e9tn\u011b:<\/p>\n

\u0161ablony budou odstran\u011bny a nahrazeny volitelnou dynamickou typizac\u00ed (pokles v\u00fdkonu nebude pro modern\u00ed po\u010d\u00edta\u010de v\u00fdrazn\u00fd)<\/li>\n
