Nest wildcards when matching file names

I’ve found fairly accidentally that wildcards can be nested. For example, consider the following structure:

.
├── version-2.9
│   ├── bar
│   ├── baz
│   └── foo
├── version-3.4
│   ├── bar
│   ├── baz
│   └── foo
└── version-3.8
    ├── bar
    ├── baz
    └── foo

If you want to match ba* in version-3.*, you’d just do:

ls version-3.*/ba*
version-3.4/bar version-3.4/baz version-3.8/bar version-3.8/baz

The shell matching logic is smart enough to “nest” the two wildcards.

What a time to be alive! :)
