Several considerations pressed the design into the current form:
1) always changing output on unchanged input is hard to debug
2) GC needs to be saved from garbage, that looks like pointers
3) missed explicit initializations should not create syntax errors
4) use hardware signalling to overcome some of the limitations 
impressed by 3).
5) more???

For me the only questionable point is numer three.
