That does not need to be so awkward. It could be done without execute,
with just

function append_struct, tx, ty
tags = tag_names(tx)
tmp=create_struct(tags[0],[tx.(0),ty.(0)])
for i = 1, n_elements(tags) - 1 do tmp=create_struct(tmp,tags[i],
[tx.(i),ty.(i)])
return, tmp
end

This could be made in a slightly easier way in IDL 8. But I do not see
a way to concatenate in one line as you want.
