deepcopy function references a non-existant variable

openby dhylandsopened 2018-05-23updated 2019-02-21

In copy.py: https://github.com/micropython/micropython-lib/blob/f20d89c6aad9443a696561ca2a01f7ef0c8fb302/copy/copy.py#L163 the deepcopy function references the variable dispatch_table, which isn't initialized.

SO? The issue is still present, and it's really unpleasant

I just reported this on pfalcon's repository which is the "official" source of this repository.

minor typo in deep copy

I came across this when compiling against copy.py, looking to use the deepcopy function

File "/lib/copy.py", line 194, in deepcopy
NameError: name 'dispatch_table' is not defined

I believe it should be _deepcopy_dispatch
