Summary	0000049: Computed struct name lookup should be smarter
Description	Assume: 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

Gnomi 2019-08-29 21:41 manager ~0002478	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.
