> hacks like “we will always have this struct in another one with a pointer preceding A struct embedded within a different struct gives simply a bigger struct, which is something we have decided is a good idea (as opposed to e.g. attribute lookup in dynamic scripting languages). The unfortunate thing is that there is no way to check statically that an inner struct that you hold in your hand is indeed embedded within a larger thing. But that is the kind of assertion that is incredibly hard to prove in a simple framework without complicating things, so the better idea seems to not do it. (Also it's the kind of assertions that seldom wrong once you've tested a tiny bit). > (text based macros are simply the worst thing ever) Are they? Consider how many actual bugs were caused by text macros, and then consider how many useful things you can do with them that you simply cannot do with AST based macros.
