Many programming languages have the concept of _keywords_, special syntax items that are not just identifiers reserved by some library, but words reserved by the language itself.
The challenge is to write a minimal program for a language with such keywords, with as few characters as possible (code golf), while at the same time using every single keyword from the language.
The program need not do anything meaningful or perform any particular input/output, but it most compile cleanly with a conforming compiler and execute without run-time errors/crashes. Non-standard extensions and alternative non-standard keywords shall not be used.
---
Example, all keywords from the C language (as per the current C17 standard):
```c
auto
break
case
char
const
continue
default
do
double
else
enum
extern
float
for
goto
if
inline
int
long
register
restrict
return
short
signed
sizeof
static
struct
switch
typedef
union
unsigned
void
volatile
while
_Alignas
_Alignof
_Atomic
_Bool
_Complex
_Generic
_Imaginary
_Noreturn
_Static_assert
_Thread_local
```

Keyword golfing

Many programming languages have the concept of _keywords_, special syntax items that are not just identifiers reserved by some library, but words reserved by the language itself. 

The challenge is to write a minimal program for a language with such keywords, with as few characters as possible (code golf), while at the same time using every single keyword from the language.

The program need not do anything meaningful or perform any particular input/output, but it most compile cleanly with a conforming compiler and execute without run-time errors/crashes. Non-standard extensions and alternative non-standard keywords shall not be used.

Example, all keywords from the C language (as per the current C17 standard):

```c
auto  
break  
case    
char  
const

double  
else  
enum  
extern

goto
