Re: Small survey on the usage of the metaclass system and MOP

Hi Jochen,

we do not use any of these Groovy features - why is that information 
relevant to you ?
If you are gauging if you can remove some potentially unused features 
from Groovy, it might be best to state so - nothing to get people to 
take the time to reply, than to tell them an important feature of their 
language might be cut (or trimmed)... ;-)

Cheers,
mg
