Hello my name is Sebastián Krynski from Buenos Aires, Argentina.Just writing to let you know that I'm starting to work on adding an atomic swap operator in Pharo , guaranteed not to be interrupted by the VM. The operator will be used this way:a :=: bmeaning 'swap variable a with variable b'.In order to do this I will be modifying the VM and the Compiler .I'm working under the direction of INRIA and Gabriela Arévalo.
