Why isn't there an "un-ld"?  Doesn't anyone think it would be useful
to take a linked executable and tear it to pieces?

Or is this a nasty no-no, like disassemblers and decompilers and other
reverse engineering tools?

Or is it just too expensive to have a decomposable a.out format?  (Is
it impossible to decompose current a.out formats?)
