That won't work. Then I will get what the VALUE of $bar is set to. I want
the actual text "bar". Basically everything after the "$" -- ie. The NAME of
the VARIABLE, not it's contents.
The closest I've come so far is to do this.
Function myname($foo)
{
echo "variable named $foo has the contents $$foo";
}
Myname('bar');
Which is pretty lame.
