Summary0000049: Computed struct name lookup should be smarter
DescriptionAssume:

  struct Door { int flags; };
  struct Exit { int flags; };
  struct Room { struct Exit north; struct Exit south; };

  struct Room room;
  string dir;

  room->(dir)->flags;

This line throws a compiler error that 'flags' is defined in multiple structs (Door and Exit), even though the compiler could deduce that Exit is meant - because Room doesn't have any top-level Door members. Instead, the compiler currently considers all structs defined in scope as possible candidates.

Testcase: t-040413

Actually it is not true, that the compiler can deduce the type of a runtime struct member lookup. The given struct can be a derived struct type containing additional members with different types, that the runtime lookup should find.
