[erlang-bugs] Linter support for packages

[Joern]

Dear erlang-bugs,

following a conversation with Ulf Wiger I'd like to request a
modification of the linter to emit warnings if a non-namespaced module
is used in a namespaced module without a fitting import. I am aware
that namespace / packages are not officially supported but they are
part of the official OTP distribution after all.

This is especially a problem with trivial (and therefore usually not
test covered) case such as

_ -> error_logger:error_msg("...")

where the error that error_logger is not defined in the current
namespace will obfuscate the reason for the crash or produce the crash
all by itself.

With best regards,


Joern
