How about no headers or macros?
Textual include files are annoying and C++ needs more symbolic
modules, but not having the ability to use namespaces is
annoying too and D's take on name resolution can break code.
Maybe I should explain the namespace part, as what I am referring
to is a relatively new feature in C++ called "inline namespaces".
I basically do this in different include files:
namespace mylib {
inline namespace common {
// stuff I want to use without prefix or with ::mylib::*
}
// stuff I want to use with prefix ::mylib::*
}
When I include various parts of mylib I simply write
"use namespace ::mylib::common;"
Then all symbols in ::mylib::common is accessible without
prefixing it, but I can choose to use explicit prefixing
::mylib::... whenever I want to anyway.
Handy for not polluting the namespace, but also getting easy
access to things often used in conditional like "is_empty(x)".
Not sure if other people do this, but I like it.
