No need for macros!
Its an interesting feature request, maybe open a Github issue so people can
discuss it.
I think your solution is not terrible, you could generalize it to
readcell(f, nlines) = readdlm(IOBuffer(string([readline(f) for i in
1:nlines])))
Then do something like
f = open("mydata","r")
cells = {}
while !eof(f)
push!(cells, readcell(f, 3))
end
close(f)
