Comparing D structs

[Dan]

That sounds great, and seems like yet another reason for me to switch to D (other than the removal of header files which always seemed like a kludge).

Just for the record though, I think one can initialize/blank/calloc C structs too, but the problem is that some struct elements (of the same array) may have padding while others don't, or perhaps they have different size paddings.
