filter method not taking key_path_separator in consideration

[rbentaarit]

Python version
3.7.4

Package version
0.14.0

Current behavior (bug description)
d = benedict()
d.keypath_separator = '$'
--implementation--
print (d.keypath_separator)
d1 = d.filter(lambda k, v: True)
print (d1.keypath_separator)

$
.
This behavior makes me loose the correct structure when I have '.' in the key parameters.
Expected behavior
$
$

Thank you for reporting this issue. The same problem affects also all methods that return a new benedict instance.
I will fix this in the next release.

In the meanwhile you can fix it by doing:

d1 = benedict(d.filter(lambda k, v: True), keypath_separator=d.keypath_separator)

Thanks for the quick response : )
Unfortunately this will not work because the tree is already generated by the filter function and in my use case I have '.' in the keys which will divide them in sub trees before the constructor function.
so my fix for now :

 new_dict = benedict()
  new_dict.keypath_separator = '$'
  keys = list(d.keys())
  for key in keys:
    value = d.get(key, None)
    if True:  
        new_dict[key] = value
  return new_dict

I understand the problem, thank you for having explained it better.
