In the 1990s, the European Patent Office created a bizarre interpretation whereby "as such" is a reference to "as programs for computers", and thus the exclusion can be completely ignored if the patent application uses a name other than "programs for computers" for the claimed idea. So if I have an idea related to a program for a computer, and I want to patent that idea *as a computer implemented invention* then that's no problem. The exclusion is thus a mere formality with no substance, according to the EPO.
