I'm not really a ST afficianado yet, but I like the whole ST concept, 
and I think that this fits okay with it... but it means there should be 
a change in the explanation of side-effects and the expectation of there 
not being any. Call it perhaps "dynamic models" with "static models" 
(predictable results) being easier, but dynamic models being valid. 
There are potentially all sorts of issues with concurrency, 
repeatability, etc etc, and you need to be sure that developers know 
that those are *their* problem. Otherwise, I don't see the problem with 
dynamic models - it's potentially very useful, if subtle.
