Description JR 2022-06-08 15:40:41 UTC 
Arch/Manjaro x86_64, dmd 2.100.0.

void main()
{
    mixin("long l = ", long.min, ";");
}

// Error: signed integer overflow

int works.
Comment 1 Dennis 2022-06-15 19:24:38 UTC 
This is not related to mixin, it's how DMD converts the number to a string:

```D
pragma(msg, long(-9223372036854775808));
```

Prints `-9223372036854775808L`, with an L suffix. The problem is, the - operator is not part of the integer literal, so it's lexing `9223372036854775808L` which doesn't fit because L denotes a signed long.
