This removes
HashDict
again, and fixes some issues uncovered by basingDefaultDict
s onBase.Dict
rather thanHashDict
.Previously,
getindex
always calledget!(h::Associative, key, default)
to return a default value.When DefaultDict was based on HashDict (now deleted) and the default value was calculated using a function, a version of this function with signature
was called.
Base.Dict
has no such function (nor doesDataStructures.OrderedDict
), so the (incorrect) value returned was the function object which generated the default value, not the default value itself.Additionally, there were no tests for
DefaultDicts
with defaults generated by a function.getindex
calls thedo
function form ofget!
onDefaultDict
s/DefaultOrderedDict
s when appropriateDefaultDict
s with defaults generated by functionsEdit: Also, add back functionality for pushing tuples to
DefaultDict
s.
