Summary: dictionary type ignores argument list
Initial Comment:
In 2.2a1 the dictionary type object completely ignores
its argument list when constructing a new dictionary.
It always returns an empty dictionary no matter what
arguments are specified.
Either: it should check that it has been called with
no arguments.
Or: it should take some arguments and do something
useful with them.
I would suggest that the following arguments would be
useful:
dictionary() should return a new empty dictionary.
dictionary(d) where d is a dictionary should return a
copy of the original dictionary.
dictionary(k1=v1, k2=v2, k3=v3, ...) should return a
dictionary with keys k1, k2, k3, ... and corresponding
values.
dictionary(kvlist) where kvlist is a list of key,
value tuples should build a dictionary from the key
value pairs (effectively this is the inverse of d.items
()).
dictionary(kseq, vseq) should do the same as dictionary
(zip(kseq, vseq)) i.e. create a dictionary initialised
with corresponding elements from each list as key and
value.
Any other arguments to dictionary should be rejected.
