So if there is enough space to express the dependency with the current
syntax, is it worth introducing a new shorthand for it then?

Also for this example, why does 2:2.5 expand to 2.7, 2.6 and 2.5?  I
would have expected 2.0 ... 2.5.  Maybe the language isn't as intuitive
then as Sebastian pointed out.
