Make runtime.function(pc) public?

Given that runtime.Caller() and runtime.Callers() return a PC, shouldn't
debug.function() be public? 

runtime.FuncForPC() is already public. But apparently that's not good enough for
debug.Printstack() which indirectly calls debug.function().

Comment 1:

If you really need that code, copy it out. It's 20 lines and not doing anything special.
debug.Stack is deprecated anyway; use runtime.Stack.

Status changed to WorkingAsIntended.

Comment 2 by rocky.bernstein:

Ok. What's the equivalent of debug.Printstack()? Writing code around runtime.Stack? If
so, wouldn't it be nice to have something simple like debug.Printstack()?

Comment 3:

The equivalent is
buf := make([]byte, 10000)
n := runtime.Stack(buf, false)
stack := string(buf[:n])
and then do what you like with it.

Comment 4 by rocky.bernstein:

Yep. And if you put that in a block, buf and stack will get garbage collected more
easily. Or maybe change the stack := string(..) to a fmt.Println() and import "fmt" if
it isn't there already. And presto, you have something like (the deprecated?)
debug.Prinstack()! 
Simple things should be done simply; printing the callstack is useful enough that for me
it warrants a routine. 
But that said, it's a judgement call whether this warrants adding to the standard
library in non-deprecated way.
