R is not C/C++. In general, one does not expect to explicitly handle
memory allocation and release when programming in R. Treating
connections differently, when there is no longer any technical reason
to do so, is surprising.

I agree that it is easy to forget. It is especially easy if one
creates so-called anonymous connection references like
readLines(file(path)) -- this anonymous idiom seems nature to me when
coding R and it would be nice to make it work for connections.
