I should add, compiler identifying cases where:

1) An allocation doesn't need to be put into the GC (ie it could be 
placed on the stack.)
2) Compiler work out at compile time when a particular piece of memory 
could be deleted (rather then complete GC).  Ok we have auto however I'm 
talking about places where this can't be used.

Of course what these cases are, needs more thought (and could be 
optional).  However this is no where near the top of my performance wish 
list.
