unstreamM is not exported

[yongqli]

We are trying to write a scanlM and scanrM for vector, but to do so it seems that we need unstreamM, which exists in Generic.hs but isn't exported. Is there a reason why it isn't?

[Shimuuar]

Yeah. I wanted unstreamM too on few occasions.

Is there opposition to exporting unstreamM? It is necessary to writing monadic folds etc.

We also have unstreamPrimM which is used only for RULES-based specialization of unstreamM (#208 is related)

probably fine, though i'll have more head space to think about it in a few weeks after i recover from this release :)
