Why, for example, maps but array?

[Michael P.]

When writing Erlang, my brain always produces:
array, filename, list, map, ..., but not:
lists, maps, proplists, sets, ....

I cannot imagine that anyone applies the
general concept of 'module deals with lists'
to writing a concrete line of source code.

To me `+` is 'addition', not 'additions'.

There is even orddict but ordsets ...

... that corresponds to dict but sets.

The decision seems to depend on author
and some tossing of coins.

Can there be learned anything from that?
