Is it possible to get the name of a function and the names of the function

Name of a function? Yes.

It has to be used at compile time with an alias of course, but it works.
I'd like to pass several functions at once. Is there a way to make this
variadic? The obvious approach (writing "NameOfFunc(alias f...)") fails
with a syntax error.
Name of params? No, not that I've found. Sometimes the compiler will
give parameter names of functions declared with tuple parameters in
error messages; I wonder if that could be abused.
Don't you love it? "Most C++ template features are discovered." So are D's.
