Cazacu Mihai commented on GROOVY-7927:
--------------------------------------
Can you estimate a ETA for this issue, please? I have hundreds of classes that
are negatively impacted by it and I'm in a situation where I have to think if
switching back to Java is an alternative in order to keep the deadline of the
project. Using "as" in each of these classes it makes the code too ugly.
Thank you!
