Ambiguity method error when one method can't be applicable

[Vicente-Arturo Romero-Zaldivar]

Hi Anna,

Sorry for the late reply, I guess I lost the track of this issue.

The chageset you have mentioned implements a new approach to unstick 
lambda expressions which has been discussed a lot in this list.

Check for example [1] and other mails in the thread.

Thanks,

Vicente
