-## Gen's DSL

-If you don't mind a low amount of macros (~80 sloc), a DSL may be optionally defined with:
-
-```cpp
-GEN_DEFINE_DSL

-
-Using the previous example to show usage:
-
-```cpp
-Code type_ns(uw)           = type( uw );
-Code type_ns(allocator)    = type( allocator );
-Code type_ns(string_const) = type( char, specifiers( Const, Ptr ) );

-    body = ArrayHeader.body();
-    body->add( variable( uw,        Num       ));
-    body->add( variable( uw,        Capacity  ));
-    body->add( variable( allocaotr, Allocator ));

-// Or using parse!
-Code type_ns(uw)           = type_code( uw );
-Code type_ns(allocator)    = type_code( allocator );
-Code type_ns(string_const) = type_code( char const* );

-Code header = struct_code(

-        allocator Allocator;

-`type_ns` is a helper macro for providing refering to a typename if using the c-namespace naming convention.
