Maybe get() is wrong in MapCSS

[naoliv]

Have any object with species (for example, species = Foo bar).

Use this example to validate it:

*[species] {
        throwWarning: tr("{0}", split(" ", tag(species)));
}

After validating we can see a warning about [Foo, bar].
So right, we can split the value in a list with two values.

Now suppose I want to get the first element from this list.

From what I understand from https://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation#Evalexpressions it's just necessary to use get(lst, n) where lst is the list (which we already have it above) and n the element, starting at 0:

*[species] {
        throwWarning: tr("{0}", get(split(" ", tag(species))), 0);
}

But with this we can only see a message saying null.
Using 1 as the element number also gives the same problem.

For this example I would like to get the Foo value only.

Am I missing something here, there is some detail about get() that is not documented or it's not working as expected, please?

The closing parenthesis of the get() is at the wrong position. It must be after , 0

correct syntax:

*[species] {
        throwWarning: tr("{0}", get(split(" ", tag(species)), 0));
}
