 Some C features are footguns by default, so Crowbar ensures that they are only used correctly.

 

--   Unions blah blah blah

+-   Unions are not robust by default.

+    Crowbar only supports unions when they are [tagged unions](tagged-unions.md).

 

 C's syntax isn't perfect, but it's usually pretty good.

 However, sometimes it just sucks, and in those cases Crowbar makes changes.

 

--   Complicated types (function pointers, pointer-to-`const` vs `const`-pointer, etc)

+-   C's variable declaration syntax is far from intuitive in nontrivial cases (function pointers, pointer-to-`const` vs `const`-pointer, etc).

+    Crowbar uses [simplified type syntax](types.md) to keep types and variable names distinct.

 -   `_Bool` is just `bool`, `_Complex` is just `complex` (why drag the preprocessor into it?)

 -   Adding a `_` to numeric literals as a separator

+-   All string literals, char literals, etc are UTF-8
