Hello developers.
I like the star expression.
It would be even better if we could extend the idea of PEP448 to
provide the following syntax at the time of assignment.
``` python
a, b, d, **_ = **{"a":0, " b":1, "c":2}, d=3
# Expressed as a function, it looks like this:
def func(a, b, d, **_):
...
func(**{"a":0, " b":1, "c":2}, d=3)
```
This is useful for splitting the dictionary
Ideally, it would be nice to be able to provide the same syntax when
calling the function.
I think this applies to the zen of python called "There should be
one-- and preferably only one --obvious way to do it.".
``` python
a, *args, b, **kwargs = 1, 2, *[3,4], **{"b", 4}, c=4
(
a: str,
*args,
b: list = [],
**kwargs
) = 1, 2, *[3,4], **{"b", 4}, c=4
func = lambda(
a: str,
*args,
b: list = [],
**kwargs
): print(a, b)
```
But it would be difficult because it would conflict with various
syntaxes(etc. PEP 3132).
We may have to declare it explicitly to avoid confusion.
``` python
# etc
a, b, *args, c = (1, 2, 3, 4, 5)
```
For example, prepare a keyword for unpack the positional arguments and
keyword arguments at the same time.
``` python
a, *args, b, **kwargs = ***(1, 2, *[3,4], **{"b", 4}, c=4)
```
I hope this is an idea to develop python.
Thanks.
