You can't do that, the size of items in representation clauses have to be 
static (that is, known at compile-time). It doesn't make sense to specify 
the location of something of unknown properties.

Note that by giving all of the other components, you effectively place the A 
component in a particular location (the one left over). But I'd suggest 
using some sort of static data structure.
