OnRelease, loops, level10 v level10.button ???

Question

After looking at some of the previous onRelease/for loop
topics, I'm still stuck. I have 26 buttons for 26 letters in the
alphabet. The buttons are defined on the stage already (they look
like they're drawn in chalk, oh boy!). I'd like to do a loop to set
onRelease for all the buttons. Each button's instance name is a
single alphabetic character, which I thought I could use to
identify which button was pressed ("A", "B", "C"...). So I set up
this loop:
for (var thing in this) {
if (this[thing] instanceof Button) {
// the alphabet button names are one character long
if (this[thing]._name.length == 1) {
this[thing].onRelease = function():Void {
// thought the button name, which is a letter, would be
passed as arg
letterPressed(this._name);
Unfortunately, the "this" in on release is at level10, not at
the button level (it's at _level10, not _level10.A, _level10.B,
etc). It's as if the onRelease was not called in the main timeline,
and no longer knows what button called it. It's the same as if I
directly selected the button in the flash editor, and called
on(release) in the actions panel.
By the way, I did try setting an id into the button within
the loop, but that doesn't help, since "this" doesn't point to the
right thing.
If I overtly set onRelease like this:
A.onRelease = function() { trace(this._name)}
I get "A", which is what I want. So.....how can I set these
in a loop, but have the onRelease behave like it's set in the
timeline (which it is), and not as if it's set down in the button?
It would be really handy if I could use the for loop, and not have
to call 26 separate onReleases. Any help would be appreciated.
Thank you.
