Yeah but if it's been declare'd -r (readonly) that isn't an issue. 

Personally I think access to all the variables is fine; an ebuild is a
shell-script, not a C++ project, and if a dev breaks something it's his
responsibility to fix it. (Quite apart from this review process picking
stuff up.) My 2c on that.

Wrt to the function, I'd define it so:

use_linguas() {
        (($#)) || die 'use_linguas() called with no arguments'
        ALL_LINGUAS=
        local lingua
        for lingua; do
                use "linguas_$lingua" && ALL_LINGUAS+=" $lingua"
        done
        # [[ $ALL_LINGUAS ]] || die 'No Linguas available'
        [[ $ALL_LINGUAS ]] && return 0
        # ALL_LINGUAS=en # default to English
        return 1
}
..to call with use_linguas de en es it zh # for example

It'd be easier to maintain if the ebuild author wrote:
MY_LINGUAS='de en es it zh'
..at the top of the file, with calls to:
use_linguas $MY_LINGUAS
..where needed.
