Can a Range evaluate to False in Bool context in Raku?

Question

While making use of a Range to solve a problem I noticed that a Range with 0 elems would be True as a Bool. In what scenarios could a Range be False?

[0] > (^0).so
True
[1] > (1..0).so
True

The behavior does not match the design docs up to Raku v6.d, an empty Range is expected to be False. This is being addressed with Raku v6.e.

[0] > use v6.e.PREVIEW
Nil
[1] > (^0).so
False
[2] > (1..0).so
False
