The answer is not only no, but heck no. Compilation in any language is
intrinsically a one-way, lossy transform. Asking for a decompiler that can
recreate the original source code is exactly the same as asking for a
mechanism to retrieve the original set of numbers that went into a
calculation -- if you only have the average of those numbers now. In each
case, there are an infinity of sets of original sources that could be *the*
original source, and no way to distinguish among them.
