Concurrency planning

My (Ola Bini) current thoughts on concurrency

futures with agents, like Io, agents are a thread pool, futures become the real value when needed. agents can be spun off too. use some other syntax since @ is taken. lazy operator is a lexical kinda thing that just does the operations inside it when it's needed. a future implemented in terms of aspects:

 
Future before(:any, except: [:become, :forceResult], 
              self become(self forceResult))
