Ah, yes, there is a confusion between "side-effect" from the pure 
function point of view and "side-effect" from property 
functionality point of view. I'd say that property setter should 
be a pure function with one exception : it is allowed to changed 
"this" fields. No global state changes, no calls to impure global 
functions, not even calls to "this" non-property functions.
