当然不是，如果他们这样做，他们将是多图而不是地图。

Of course not, if they did they would be multimaps and not maps.

我有一个地图的行为就像它是一个多图。两个键是

相同。编译并按预期运行。

I have a map that behaves as if it were a multimap. Two keys are the
same. Compiles and runs as expected.

我有一张行为与地图相同的地图如果是多图。两个键是

相同。按预期编译和运行。

等等......也许我误解了地图。它是独一无二的k，v对还是只有

唯一键？如果它是前者，那么这将是有道理的。我的印象是后者。

Wait... perhaps I misundersatnd maps. Is it unique k,v pairs or just
unique keys? If it''s the former, then that would make sense. I was under
the impression it was the latter.
