Hi,

According to the documentation, the meaning of the first argument is the 
first value and the second one is the *final* value of the sequence not 
the length of the sequence.
I think that your proposition will break a lot of code.


Some example of lists:seq usage.

Erlang (BEAM) emulator version 5.6.3 [source] [smp:2] [async-threads:0] 
[hipe] [kernel-poll:false]

Eshell V5.6.3  (abort with ^G)
1> lists:seq(2,3).
[2,3]
2> lists:seq(2,0,-1).
[2,1,0]
3>
