May be that this works as intended, but it fooled me:

void main() {
int[5] a = 0;

randomShuffle(a);
Fixed-length arrays are value types. 'a' is copied to randomShuffle() so
its copy is shuffled. Passing a slice of the whole array works:
randomShuffle(a[]);
writeln(a);
randomShuffle(b);
writeln(b);
}

In DMD 2.0.59 the fixed-size array "a" won't be shuffled (the dynamic
array "b" will), and you won't get any warning about it.
I'm not sure whether this counts as something that should be reported as
a bug/improvement, nor if only randomShuffle() displays this behaviour,
perhaps you could enlighten me.
