Ah, that's great, sounds like we are allies, for example when arguing for "let it crash" and other take aways from the Erlang error reporting philosophy in the Julia community.
And thus we who transitioned to Julia from R and know a bit about martingales and less about programming have long been trying to degrade the core of the language and its principles by making `mean` a Base function.
I would never put in 45s by pressing buttons, it seems we are alike there. But I would put 45 sec in with a (rotary) time control knob though, maybe you want to reevaluate.
The notions first index, current index, previous index, next index and last index and each index are all invariant under shifts of the index set... yet this is the hill people choose to die on.
Some abstractions are costly if the compiler doesn't optimize them away, so one use is to check if that happens. So one iterates changing the Julia code, not the machine code mostly.
Thank you, that resonates
