On: ROOT: analyzing petabytes of data scientifically

[ephimetheus]

uproot to this day doesn’t properly implement reading TEfficiency, I believe, which is a bummer, to be honest.

[sbinet → ephimetheus]

that's odd. TEfficiency is a relatively simple thing to read/write :

[ephimetheus → sbinet]

Yeah I think it has to do with the memberwise splitting. https://github.com/scikit-hep/uproot5/issues/38

I understand this has not been a priority so far.

It kinda works if you open a magic file with a specific on-disk representation which bypasses this, but that’s not a solution at all.
