Could we some day start a discussion on the state of error reasons in Erlang/OTP?

Some things are very clueless like discrepancies between the shell and compiled code ([ X || X <- [1], _ = foo ]), non-obvious discrepancies between some filters (replace _ = foo by just foo in previous example) or even plain useless error reasons like {badrecord,foo}.

Could that be gradually improved on a large timescale?
