^^^^^^^^^^^^^^^^^^^^^^^^
I'm afraid that statement is false for all values of "something" :)
Could you just look through the lexical scope of the object?
for $this.MY.kv -> $k, $v {
print "$k: $v\n"
}
Or would you look through the class's lexical scope and apply it to
the object?
for keys $this.class.MY {
print "$_: $this.MY{$_}\n"
}
I think one of those two is possible. (Providing the .class method
exists and DWIMs)
