Global extension function in kotlin : <p>Hey I want to make a class in kotlin that will hold all extension functions that I will use in a few places for example:</p>

<pre><code>class DateUtils {
    //in this case I use jodatime
    fun Long.toDateTime() : DateTime = DateTime(this)
    fun String.toDateTime() : DateTime = DateTime.parse(this)
}


class SomeClassWithNoConnectionToDateUtils {
    fun handleDataFromServer(startDate: String) {
        someOtherFunction()
        //startDate knows about toDateTime function in DateUtils 
        startDate.toDateTime().plusDays(4)
    }
}
</code></pre>

<p>Is there a way to perform such operation </p>
