Great suggestion! It's brilliant! Using sequences to address sequeces...
mmm... terrific! With this enhancement you can do 100% dynamic
data strucutures. Note that you can still use the old (current) way:

s = {{1,2,3,{4,5}}}
s1 = s[{1,4,1}]    -- s1 = {4}
s2 = s[{1,4}][1]   -- s2 = {4}
s3 = s[1][4][1]    -- s3 =  {4}

No code breaking!!!

Another suggestion that comes to my mind:

s = {a,b,c,d,e}
s1 = s[~..{1,3,5}]    -- s1 = {a,c,e}
