I think we may meet the requirements of matching 0-1 level in the future, then
*** may be not a good design.
As a single * stands for exactly 1 level now, we can define *{start, end} to
[start, end) levels, {x} to exactly x levels and {*} to arbitrary levels, where
** is just a short
Hi,
- if only for 0 or more layers, I opt for ***
- if we want to define a clear range of layers, I opt for *{start, end} or
**{start, end}
