[issue38517] functools.cached_property should support partial functions and partialmethod's

[Tal Einat]

Tal Einat  added the comment:

Note that it is already possible, though awkward, to create cached properties 
dynamically. Using the example from PR GH-16838:

class ProcNet:
pass

for proto in ('icmp', 'icmp6', 'raw', 'raw6', 'tcp', 'tcp6', 'udp', 'udp6', 
'udplite', 'udplite6'):
@cached_property
def prop(self, *, proto=proto):
with open(os.path.join("/proc/net", proto)) as file:
return file.read()
setattr(ProcNet, proto, prop)
prop.__set_name__(ProcNet, proto)

IMO this is good enough, considering that this is all pretty much required for 
dynamically creating normal (uncached) properties and other types of 
descriptors.

functools.cached_property should support partial functions and partialmethod's

This way one can create cached_property's dynamically.
