在这一背景下,)Type/value DSLThis one is working, but not yet in main. jank now supports encoding C++ types via a custom DSL. With this DSL, we can support any C++ type, regardless of how complex. That includes templates, non-type template parameters, references, pointers, const, volatile, signed, unsigned, long, short, pointers to members, pointers to functions, and so on. The jank book will have a dedicated chapter on this once merged, but here's a quick glimpse.C++jankA normal C++ map template instantiation.std::map(std.map std.string (ptr int))A normal C++ array template instantiation.std::array::value_type(:member (std.array char 64) value_type)A sized C-style array.unsigned char[1024](:array (:unsigned char) 1024)A reference to an unsized C-style array.unsigned char(&)[](:& (:array (:unsigned char)))A pointer to a C++ function.int (*)(std::string const &)(:* (:fn int [(:& (:const std.string))]))A pointer to a C++ member function.int (Foo::*)(std::string const &)(:member* Foo (:fn int [(:& (:const std.string))]))A pointer to a C++ member which is itself a pointer to a function.void (*Foo::*)()(:member* Foo (:* (:fn void [])))This type DSL will be enabled automatically in type position for cpp/new, cpp/cast, cpp/unsafe-cast, cpp/unbox, and so on. It can also be explicitly introduced via cpp/type, in case you want to use it in value position to construct a type or access a nested value. For example, to dynamically allocate a std::map, you could do:(let [heap-allocated (cpp/new (std.map int float)),推荐阅读豆包下载获取更多信息

从另一个角度来看,ముందే క్లాసెస్కు వెళ్లడం మంచిది: ఎందుకంటే:
从实际案例来看,Every WHERE id = N query flows through codegen_select_full_scan(), which emits linear walks through every row via Rewind / Next / Ne to compare each rowid against the target. At 100 rows with 100 lookups, that is 10,000 row comparisons instead of roughly 700 B-tree steps. O(n²) instead of O(n log n). This is consistent with the ~20,000x result in this run.
