>(That would imply moving string_view.tcc to another directory).
I'm thinking about adding an include/experimental/bits directory
again, for internal pieces of the Networking TS.
I didn't do it last time because I was too lazy, but as I'm adding
more non-public headers to include/experimental I think it makes
sense.
That patch looks like this, plus moving erase_if.h, string_view.tcc
and fs_{dir,fwd,ops,path}.h to the new bits sub-directory.
Anyone else got an opinion?
