In case statement, case nil and range

[nemorami]

this code doesn’t compile.

ch = nil
case ch
when 'A' .. 'Z'
  puts "ch is capital"
when Nil
  puts "ch is nil"
end

In case statement, if no range expression, it is compiled successfully.

Put the when Nil first, would be the easiest way to fix this.
