It would be helpful to have variable-length methods of any, all, and count for comparing collections, so that e.g. you could write this: all(≡, \[1,2,3\], \[1,2,3\]) # true count(≥, (3,2,1), 1:3) # 2 Proof of concept: Bas…

I was just wondering if there is a nicer way to do practically this: reduce( (d, c) -\> (d\[c\] = get(d, c, 0) + 1; d), "ACCACD", init=Dict{Char, Int}() ) hence, to do a non-binary count s = "ACCACD" Dict( c =\> c…
