Wrong. Just because a language-spec says a compiler writer does 
not have to care about a particular type of input does not mean 
that the compiler and programmer cannot verify the data to be 
valid.

But hey, you don't even acknowledge that there is a difference 
between the machine and the program, so no hope of you getting 
into a reasonable argument on this one. ;-)
