static if ( is(abc U : U[]) )

... aliases U to whatever abc is an array of.
In the case of an associative array, is it possible to retrieve both the value and key type? (D1)

template AAKeyType(T) {
    alias typeof(T.keys[0]) AAKeyType;
}

template AAValType(T) {
    alias typeof(T.values[0]) AAValType;
}

Thanks ^^ But I actually asked my question wrong ; I also need to check whether abc is an associative array or not.

Adapted from the module tango.core.Traits:

template IsAA(T) {
    const bool IsAA = is( typeof(T.init.values[0])[typeof(T.init.keys[0])] == T );
}
