Further reduced to no longer require Phobos:

--- sing.d
module sing;

alias I(alias A) = A;


--- git.d
import sing : I;


--- manager.d
module manager;
import git;

template all(alias pred = "a")
{
    bool all(T)(T range)
        if (is(typeof(I!pred(range))))
    {
        return false;
    }
}

class DManager
{
    void getCacheState(string[] history)
    {
        string[] componentNames;

        foreach (submoduleCommits; history)
        {
            componentNames.all!(componentName => componentName.I!(component =>
component));
        }
    }
}
