Would you give a real-world example, from an existing application, of 
half-open not being convenient?

The point of pulling some range out from a set is to slice the set. 
Slices shouldn't overlap.  If some program is using overlapping slices, 
the programmer was probably not conscious of this overlap, and it may 
well be a bug in the program.
