--- Comment #11 from Bolpat <qs.il.paperinik at gmail.com> ---
As Timon pointed out, requiring the evaluation of the assert msg to be nothrow
is a limitation, I don’t think it is a major limitation. `assumeWontThrow` [1]
is well-suited for this purpose.

I don’t think that
```d
import std.exception : assumeWontThrow;
assert(condition, assumeWontThrow(potentially throwing expr));
```
is too much to ask for. It documents clearly that the message-generating
expression could throw. That way, an Exception thrown by the message-generating
expression does not hide a bug.
