The following question was asked on the main site: How to pronounce 'll after ll?
Despite the question being based on something read on a book, I think that pronouncing a word ending with ll followed by a contraction of will is still possible nowadays.
Maybe people avoid saying "Jill'll come later." and prefer saying "Jill will come later." (I doubt that), but how can a English learner know that he is asking for the pronunciation of something that is rather rare to say in English?
