That's no problem. Hyphens would also circumvent the Network.URL problem :)
Of course, you'd have to set up a not-too-complicated way to type \x2010 in your editor.

Sure, mate, that's absolutely not going to be a bitch :-/
(.<<.) = shiftL
(.>>.) = shiftR

Also map_m and fiter_m &c? And map_m_, for_m_ ?
Resp. shift-l, map-m, map-m_ ?
Would that be
4) flatten, when followed by lowercase letter, nothing or underscore?

Okay, let's start to find it. We won't find something which is perfect in all cases, but
perhaps something that's good enough in almost all cases and never too ugly.
Should aBC... -> a_BC... / a-BC... in all cases? If not, in which cases what other
Should aBc... -> a_bc... / a-bc... always? If not, what else?
aB -> a_b /a-b ?
aB' -> a_b' /a-b' ?
aB_ -> ?
aB'c... -> ?
aB'C... -> ?
