[Note, just to compare: in Lua, this little magic making builtin sequences

one would write explicitely, resp.:
for key,val in pairs(t)
for item in ipairs(t)
where pairs & ipairs resp. create iterators for (key,val) pairs or indexed items
of a table (used as python lists or dicts). Functions pairs & ipairs are
builtin, but it's also trivial to make iterators (or generators) in Lua, since
it has 'free' objects we don't even need classes for that.]
Read instead:
for _, item in ipairs(t)
for idx, item in ipairs(t)
Lua's builtin 'ipairs' returns both index and item.
