The following seems redundant because the other isFloatingPoint!E
version uses the default arguments 0 and 1 anyway.
auto ref randInPlace(E)(ref E x) @trusted if (isFloatingPoint!E)
{
return x = uniform(cast(E)0,
cast(E)1);
}

The following works if you pardon the name foo. :p
auto foo(TT)(ref TT x)
{
foreach (ref e; x)
{
e.randInPlace;
}
return x;
}
/** Generate Random Contents in $(D x).
*/
auto ref randInPlace(R)(auto ref R x) @safe if (hasAssignableElements!R)
{
return foo(x);
}
/** Generate Random Contents in $(D x).
*/
auto ref randInPlace(T)(ref T x) @safe if (isStaticArray!T)
{
return foo(x);
}
Alternatively, a string mixin could be used but they should be reserved
for when there is no better solution.
