You obviously haven't seen enough music notation. ;-) It's not at all unusual in some sorts of music to have both a solid and an open note head on the same stem. Standard staff notation is obviously very limited in what can be done with this, but combining a quarter and a half note on a single stem is easy, and isn't at all unusual. With L:1/8, the notation [A4ce]2 is a case that works. The resulting A8 is a whole note, so it doesn't have a stem. So the [c2e2] would be two quarter notes on the same stem, and the A8 would be a stemless whole note drawn directly below them. The simpler [A2c]2 would be a half-note A and a quarter-note c on a single stem. These aren't at all odd or unusual notation. Of course, it's very easy to come up with examples in abc that have no representation in staff notation. You can't mix quarter and eighth notes on the same stem. But in any case, this is a secondary issue. The simple case of [Ace]3 is easy, and some people would like it to work. Similarly, the [ce]>[Bd] case is very useful, and already works with some abc software. In fact, are there abc programs that reject [ce]>[Bd] now?
