[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] | |rg Component|dmd |phobos --- Comment #1 from [email protected] --- Nope, this is an issue with the toString detection in phobos. dmd reports an error if the template constraint fails to compile (see https://run.dlang.io/is/9g2V1G). The problem is that phobos uses speculative compilation to detect if a struct defines toString - which swallows the aforementioned error message. --
