Unexpected benefit from using #Python 3.10’s match/case syntax:
I replaced code that was essentially equivalent to
```
axes = {
CARTESIAN: ("x", "y", "z"),
CYLINDRICAL: ("r", "theta", "phi"),
}[geometry]
```
with
```
match geometry:
case CARTESIAN:
axes = ("x", "y", "z")
case CYLINDRICAL:
axes = ("r", "theta", "phi")
```
Which is equivalent, right ?
But the *coverage* is not necessarily so !
