zip doesn't print a proper error message if streams aren't of equal length

[sternenseemann]

Consider, e.g. ,[(x . y)] {ix>1}{`0} $0, it will just print the following for jacinda 3.3.0.1:

ja: src/Jacinda/Backend/T.hs:(580,6)-(584,44): Non-exhaustive patterns in case

Should probably make it clear what is going on. (Note that I'm not sure whether streams that return an unequal amount of elements is the only way to trigger this.)

the only way to trigger this

I've also managed to trigger this in a situation where the streams return the same amount of elements.
