Re: help with weak references

Thanks for nailing this Jasper-M. 

A class (versus case class) is necessary, and if one really wanted to bind 
variables one could use a var as in:

var x = wr.get.get
x = nullSystem.gc()
println(wr.get.get) // <---- prints None.

However, the above defeats having a REPL. If one were manipulating 
'big-data', then the growing lexical scope from the interactive session 
would keep holding onto inaccessible values. 

Is this a bug?
