WHATS WRONG WITH TOP POSTING IN ALL CAPS AND NO PUNCTUATION!?!?!?! :) No one has complained to the moderators that CoC is being violated. and if they did, there’s a whole bunch of safeguards to ensure that it’s not being misused. I do occasionally (once or twice a year?) place specific members

Presumably this was inspired by the other thread, "Add __keys__ or __items__ protocol", where an __items__() method was proposed instead of recognizing mappings by the presence of a keys() method. On Tue, Feb 18, 2020 at 12:46 PM Rhodri James wrote: > On 18/02/2020 20:33, Soni L. wrote: > > > >
