The parser does not complain, but yields a surprising result...
In b = a - 1, a refers to var a, which is declared afterwards. IMHO, it should refer to the parameter a of the function, since it has not been shadowed yet.... Anyway, I think:
shadowing is dangerous and should not be allowed i.e., it should not be possible to declare var a if it has been previously declared in a variable or a parameter.
in an action block, it should not be possible to refer to variables defined later on... action blocks being purely sequential...
