Ebibuuzo Ebitera Okubuuzibwa

Njawulo ki enkulu wakati wa Hindley-Milner ne bidirectional type inference?

Hindley-Milner ateebereza ebika mu nsi yonna nga tekyetaagisa kunnyonnyola kwonna, ng’akozesa okugatta okuggya ekika ekisinga okuba eky’awamu ku buli kigambo. Okuwandiika mu ngeri bbiri (bidirectional typing) kwawula enkola mu ngeri bbiri —okukebera n’okugatta —kwetaaga obugambo obumu naye nga kuwagira ebifaananyi by’ekika ebisinga obugagga nga higher-rank polymorphism n’ebika ebisinziira. Okulonda kisinziira ku oba okukulembeza okuteebereza okutegeerekeka mu bujjuvu oba amaanyi agalaga nga olina obugambo obutonotono.

Ddi nkozese Hindley-Milner type inference ku lulimi lwange?

Hindley-Milner kirungi nnyo ng'oyagala okuteebereza kw'ekika okujjuvu nga tekyetaagisa kunnyonnyola, nga bwe kirabibwa mu nnimi nga Haskell 98 ne OCaml. Kikola bulungi ku rank-1 polymorphism n’ebika bya data ebya algebra ebitereevu. Singa enteekateeka y’olulimi lwo ekulembeza obumanyirivu bw’omukugu mu bufunze, obutaliimu bunnyonnyola okusinga ebikozesebwa eby’ekika eky’omulembe, Hindley-Milner y’esinga okulonda. Mewayz ekwata ku nkola zombi mu modulo zaayo 207 ku $19 zokka/mo.

Biki ebikoma mu kukebera ekika eky’enjuyi bbiri?

Okukebera ekika mu ngeri bbiri kyetaagisa abakola pulogulaamu okuwa obugambo bw'ekika mu bifo ebimu-mu ngeri entuufu parameters z'emirimu n'ennyonnyola ez'omutendera ogw'oku ntikko. Wadde nga kino kiyinza okulabika ng’ekizibu, obugambo buno bukola ng’ebiwandiiko era bulongoosa nnyo obubaka bw’ensobi. Ekikoma ekituufu kwe kwongera ku buzibu bw’okussa mu nkola, okuva bwe kiri nti olina okunnyonnyola n’obwegendereza enkola w’ekyusa wakati w’engeri y’okukebera n’okugatta okukuuma obulungi.

Nsobola okugatta Hindley-Milner n'okuwandiika okw'enjuyi bbiri mu nkola emu?

Yee, abakung’aanya bangi ab’omulembe guno bakozesa enkola ey’omugatte. GHC Haskell, okugeza, ekozesa Hindley-Milner ng’omusingi naye ekyuka n’egenda mu kukebera okw’enjuyi bbiri okuzuula ebika eby’eddaala erya waggulu n’okugaziya okulala. Enkola eno eya layers ekuweereza implicit inference for simple code ate nga ewagira ebikozesebwa eby'omulembe nga annotations ziweebwa. Module z’okuyiga 207 eza Mewayz, ezisangibwa ku $19/mo, zitambula mu kuzimba enkola ng’ezo ezigatta mutendera ku mutendera.
