By adding the word "case" several more times.

I really wish we would just go with two-dots for exclusive, three-dots
for inclusive, and make that work consistently everywhere.

The "too similar to see the difference" argument just doesn't hold
weight with me.  Unless you're programming in a proportional-width
font the difference is pretty obvious.  Or define some other char
sequence to mean inclusive range.  Like  a ..|b  or a..:b or a..^b,
etc.
