there's no reason for the order to be "unpredictable". It would be more
reasonable to say "all all assigments are done in left-to-right order".
A smart compiler can then possibly detect that none of the variables are
duplicated and that there are no interrupts and thus it doesn't matter
what order they're done in. 

Similarly, LET should be defined so that the last binding of a variable
is the one that applies.

Would removing this ambiguity in the language seriously affect any
current implementation?
