What is the preferred naming convention for Func<TResult> method parameters?

I admit that this question is subjective but I am interested in the view of the community. I have a cache class that takes a cache loader function of type Func<TResult>, which it uses to retrieve a value from the database and store it in cache.

public static class Cache
{
    public TResult Get<TResult>(string cacheKey, Func<TResult> cacheLoader) 
    {
        // Implementation
    }
}

My question is: How should I name the function parameter?

• Should I name it like an object, e.g. cacheLoader?
• Should I name it like a method, e.g. loadResult?
• Should I explicitly refer to it as a function, e.g. cacheLoadFunction? (I don't like this.)

I'm less interested in what I should name this particular function parameter and more interested in how you name function parameters in general. What say ye, Stack Overflow community?
