If you’re like many developers and you generally use println for debugging and rarely or never use an actual debugger, then this is wasted time.

I weep for the time lost on debugging with println. Good grief. It's like having access to a time stopping ability and going "nah, I like trying to add a marker and tracing footsteps".

Yes, for multi threaded workloads there aren't many options, but most are single threaded and eschewing a debugger is bonkers to me.

Anyone who actually writes Rust code knows about tracing my friend.

We also have the ever useful #[track_caller]/Location::caller().

And it's needless to say that dbg!() also exists, which is better than manual printing for quick debugging.

So there exists a range of options setting between simple printing, and having to resort to using gdb/lldb (possibly with rr).

But yes, skipping debugging symbols was a bad suggestion.
