I have a question regarding the general term "compact" vs something more specific like "remove nil" : Could we imagine other usages on different types for "compact" ?
map / flatmap has the whole category theory behind it, making it meaningful for many different types. "Filter" is also generic, because the operation of filtering has a wide range of application. "Compact", like Tino suggested, would have the general meaning of "reducing the size by removing similar elements". Removing nils doesn't seem to be a special case of this general definition. If we give "compact" the strict definition of "removing nil", then i don't understand the need for a general term, instead of something like "dropNils" (not much longer to write).
