'Collections-Unordered' "A group of related classes"
Dictionary "A particular class"
enumerating "A group of methods that all iterate"
#associationsDo: "iterate over (key->values) pairs"
#associationsSelect: "select subset of (key->value) pairs"
#collect: "map, function applied to values only"
#do: "iterate over values"
#keysAndValuesDo: "iterate over keys and values"
#keysDo: "iterate over keys"
#select: "select maplets looking just at values"
#valuesDo: "another name for #do:, at least here"
Giving these methods a common prefix would very definitely
Take a look at lists.erl some time.
keysort/2 is in one place.
It calls keysort_1/5 and keysplit_1/8.
Now keysort_1/5 follows right after;
it calls keysplit_1/8 and keysplit_2/8,
which are 1000 lines and 1030 lines
That kind of nonsense is why I want tightly
coupled functions close together, regardless
of name, if that is possible.
This is actually a place where I would
do one of two things:
split keysort/2 and its support functions
into a separate module, and re-export it,
or split keysort/2 and its support functions
into a separate file, and -include it.
