Where can I find the code...
I have checked starship, "the vaults" and googled for a long time. either
they point to starshup(wiki) where it doesn't exists, or to dead links.
Any help would be much appreciated.

None of them are really indispensible. Map and filter cab be replaced
with list comprehensions. reduce is redundant except when multiplying a

some cases, but you don't gain any functionality.

Claiming that sum etc. do the same job is the whimper of
someone who doesn't want to openly disagree with Guido.
Could you give an example where sum cannot do the job(besides the
previously mentioned product situation?
Also, map is easily replaced.
map(f1, sequence) == [f1(element) for element i
sum(sequence[0] + [1/element for element in sequence[1:]])
I think that should work.

Well, the string that gets passed is more or less a function

You could just write the function.
