Display the name of the currently executing function

How can I retrieve the name of the function that is currently running in powershell? Here is an example of what I want:

Function write-FunctionName
{
write-host "The name of this function is: *SomethingGoesHereButWhat?*"
}

Then when I execute it, it will display this:

>write-FunctionName

The name of this function is: write-FunctioName

>

Can this be done? If so how?
