Have a look at std.traits or tango.core.Traits. The appropriate way to check is via the templates they define, since it's clearer. Looking at the source will tell you how to replicate the effect should you need to.

You can also use template specialization, which, depending on your use case, might be shorter and clearer than a static if.

template Foo(T: T[]) will specialize for dynamic array arguments.  T
will be the element type (so for int[], T will be int).
template Foo(T: T[n], size_t n) will specialize for static array
arguments. T will be the element type like above, and n will be the
size of the array.
template Foo(T: T[K], K) will specialize for associative array
arguments.  T will be the value type, and K will be the key type.
