I'd agree if arrays did decay to pointers or integers on demand
(implicit conversion).
Are you arguing that if(x) shouldn't even compile if x is a
slice? If so, I was thinking the same thing. The fact that if(x)
compiles makes sense only if you think of slice as a struct which
happens to provide a convenience cast(bool) operator (which slice
doesn't provide). The meaning of if(x) is obvious if x is a
full/real/proper reference type. But since slice is just a
half-reference, so the meaning of if(x) for slices is not
obvious, and thus, it shouldn't compile.
