At least in C/C++ you can abuse preprocessor directives to just do
```
#ifdef A BCDEFGHIJKLMNOPQRSTUVWXYZ
```
Where you can more or less just extend it as far as you want

You can use this trick with more than one statement by using semicolons. For example, this will work as well:
```
for x in range(4):print('a');print(x)
