I never used this library for anything but introspecting data structures interactively in the shell. In that environment I find it to be friendlier if I can input the paths as an atom or string. Efficiency wasn't much of a concern.
That should definitely be stated in the documentation.
I don't find [foo,bar,ugh] any harder to type than <<"foo.bar.ugh">>
or for that matter "foo.bar.ugh". Same number of characters as the
string, four fewer than the binary. foo.bar.ugh I grant you.
There is one crucial feature of Apple's key-value coding
that does not apply in the Erlang context. Each non-@ step
must be the name of an Objective C selector or variable.
That means that such steps cannot themselves contain dots
or at-signs. Erlang atoms _may_ contain dots and at-signs,
and may even do so without quoting. alpher@REDACTED is a
perfectly good Erlang unquoted atom.

Did it last night. I decided to call it #asPropertyPath rather
