Wells gives the example of "straight", "late" and "wait", which rhyme in most English varieties but, because some dialects make phonemic contrasts with the vowels of these words (specifically, in parts of the north of England), a panlectal transcription would have to encode this contrast despite it being absent for most speakers, making such a system "a linguist's construct" and not part of the grammar present in any native speaker's mind (which is what adherents of such a system attempt to achieve).
