I just learned yesterday, that the dup* methods don't work as expected, if you
use various types of AST nodes and cannot set the default AST type therefore.
They return a CommonAST node, instead of the typ, that is passed to them. I've
already found a workaround for me, but maybe using some clone() method in the
dup* methods would be better?
