Well, if command line syntax is the test, then I offer my own such
program, which I call "count".  Its command lines look like

% count by 3 from 0 to 18
0
3
6
9
12
15
18
% count from 0 to 0x1000000 by 0x100 base 16 0pad 8
00000000
00000100
00000200
[65529 lines of output elided for list consumption]
00fffc00
00fffd00
00fffe00
00ffff00
01000000
% count from 10 to 5
10
9
8
7
6
5
% 

Less Unixy than jot (and presumably seq), but perhaps a bit easier to
remember.
