Of course it is, and there are collections of letters that are pronounceable words, but it doesn't give them meaning. The equivalent in English would be a spell checker that didn't flag "douberness" and passed it along. Sure you can pronounce if if you look at it phonetically but it doesn't mean anything. It is syntactically correct but broken. VHDL has a lot of things that can be written but not actually expressed in hardware.
Sure, I've no doubt it's more common there - that's very much my understanding. The wording of the above just struck me very much as if it were meant to be hypothetical, which I found amusing given that it's nothing like.
