[Pharo-project] Understanding of new Eliot Closures

Hi! I am trying to make Glorp work on Pharo, and I having some problems. In squeak I inspect [] and I see I have a BlockContext object. In latest Pharo, I get a BlockClosure. I guess this is about Eliot changes ? Now, Glorp has 5 methods extension in BlockContext. I saw BlockContext and BlockClosure and they have no hierarchy in common. So, if I want Glorp to work in squeak and pharo I must copy all that 5 methods from BlockContext to BlockClosure? is there a better solution ? I tried the first one and seems to work ok but I don't know if it is correct. Thanks in advance, Mariano
