Fantastic, thank you! Except for what I assume is a typo in `dropdim` (we
want `splice!(v,i)`), this does exactly what I want.

Sorry for the bad formatting (getting tangled with the editor).
Additional useful code to supplement the previous note:
function dropdim(A,i)
v = collect(size(A))
splice!(A,i)
return tuple(v...)
end
# now something like this works:
# which gives the sum of the two edge planes of array A3
# something along these lines:
topleft(A,d) = tuple(ones(Int,ndims(A))...)
bottomleft(A,d) = tuple([i==d ? 1 : e for (i,e) in enumerate(size(A))]...)
topright(A,d) = tuple([i==d ? e : 1 for (i,e) in enumerate(size(A))]...)
bottomright(A,d) = size(A)
mapedges(A,d) = zip(
…but not really. Reading the docstring more carefully:
Transform the given dimensions of array A using function f. f is called on
each slice of A of the form A[…,:,…,:,…]. dims is an integer vector
specifying where the colons go in this expression. The results are
concatenated along the
Yes, probably - thanks for the tip! I'll see if I can cook something up...
