Dear Maintainer,
Currently in sid, elixir fails to load modules if they are installed
in a subdirectory of /usr/lib/elixir/lib. The list of directories looks
like the following (only elixir, mix, logger, iex, ex_unit, eex
subdirectories are included, they are actually hardcoded in
the lib/elixir/src/elixir.erl source file):
$ iex
Erlang/OTP 27 [erts-15.2.1] [source] [64-bit] [smp:16:16] [ds:16:16:10]
[async-threads:1] [jit:ns]

iex(2)>
In bookworm (elixir 1.14) all the subdirectories of /usr/lib/elixir/lib
are added to the code loading path.
I'd like to suggest a path which adds missing directories (see the
attachment). Otherwise in order to run any system-wide elixir application
(like ex_doc from elixir-ex-doc) one have to use special environment
variable like ERL_LIBS=/usr/lib/elixir/lib, which is very inconvenient.
Cheers!
