That is why the rear elements of M lenses can be so close to the film plane. However, the current batch of digital sensor technology requires the light to hit the sensor at pretty much a 90 degree angle (or much closer to it than film requires). Because the shape of a M body puts the lens so close to the would-be digital sensor, the sensor is not able to capture the desired image because the light is hitting it at an obtuse angle whereas film is able to capture the image because it can deal with that circumstance. At least, that is how I understand it. Who knows whether sensor techonology will 'catch up' with film in that regard so that a sensor could be placed in a M type body. Maybe it will happen. Right now, it is impossible.

The consensus seems to be the M lenses are not suited to fit a digital body because of physics, angle of incidence or whatever. Now I realize that some of this will be buried in the archive, but I'm lazy...I'd rather someone tell me again. ;-) If the M camera can mount an M lense, and focus on the film plane, then it seems logical that that same film plane can be a digital sensor. Am I in deep space on this?
