This was something I noticed when working on the topic/fs3 branch. This PR changes the
stream
andstreamNoScope
methods to require the result type of thePull
to beUnit
. This is thePull
equivalent of-Xfatal-warnings -Ywarn-value-discard
-- folks can explicitly indicate they want the result type thrown away viap.void.stream
.Note how many cases in fs2 itself were using a nonsensical result type -- these are vestiges of the old 0.9
Pull
API where termination has to be explicitly signaled via anOption
result type.
