next

[pmp-p]

idea:

pkpy next should be called "iter_next" instead as its behaviour is radically different (does not raise) from CPython's next()

next(iterator[, default])
    
    Return the next item from the iterator. If default is given and the iterator
    is exhausted, it is returned instead of raising StopIteration.

that way it is easy to provide a similar function to other pythons
and keep codebases consistent.

to test

import builtins
builtins.iter_next = next
def next(it, default=0xdeadbeef):
    itrv = iter_next(it)
    if itrv == StopIteration:
        if default == 0xdeadbeef:
            raise itrv
        return default
    return itrv

builtins.next = next
