what's the closest thing we have in D? can we make it without
compiler builtin?
if you just want to use an assert, the compiler flag
`-checkaction=context` basically gives you this kind of error
messages.
Example how to use in DUB (from serve-d):
https://github.com/Pure-D/serve-d/blob/84094fade433f3d52e43c5296d20af53b102ffdd/dub.json
```d
void main()
{
assert(1 + 1 == 2);
assert(1 + 1 == 1);
}
__EOF__
Sample output:
core.exception.AssertError@onlineapp.d(4): 2 != 1
----------------
??:? _d_assert_msg [0x563912072788]
./onlineapp.d:4 _Dmain [0x563912069f54]
```
