Lets say I gather Diag data, which I conditionally print during testing. Are you saying that I cannot leave the diag code in place after I comment out the print function? Thats unproductive and a major obstacle to using Zig. I’m still pissed at Andrews stance of preventing Tabs, operator overloading, polymorphism, and this just seals my “stay away” stance. I really do want to like Zig, but cannot.
You don't need to comment out the print function - it could gate its behavior on a comptime-known configuration variable. This would allow you to keep your debug variables in place.
