No, I only suggest(ed) to change the documentation,
may to "unsafe coercions of ordered lists". (The
name "formDistinctAscList" is compelling enough)

Well, no problem, only my wrong assumption (and an argument to use
"unsafe" functions for efficiency), don't change the implementation.

Maybe the infix (or suffix) "Asc" could uniformly indicate the unsafe
nature of a functions. So delete toAscList and have fromAscList and
mapAsc as unsafe versions of fromList and map resp. (forget Set.image)
