an array U[] and U is not immutable;
a reference to a class or interface type C and C is not immutable.
an associative array that is not immutable.

				enum hasAliasing(T...)
				 = anySatisfy!(hasAliasingImpl, T);

Example

struct S1 { int a; Object b; }
struct S2 { string a; }
struct S3 { int a; immutable Object b; }
struct S4 { float[3] vals; }
static assert( hasAliasing!S1);
static assert(!hasAliasing!S2);
static assert(!hasAliasing!S3);
static assert(!hasAliasing!S4);
