The newlines and tabs aren't needed either :)
python -c "a,b=1,1;exec('while 1: print a; a,b=b,a+b')"
Next we get rid of that unnecessary multiple assignment at the beginning
and use long ints to avoid the overflow error:
python -c "a = b = 1L; exec('while 1: print a; a,b=b,a+b')"
It would be nice to get rid of that exec, too...
