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.

I have to admit I still readily reach for dbg! to narrow down where the problem is happening (instead of endlessly stepping through), especially in async. But when I do I put in one or two a function and upto one an await. Then I make a breakpoint before that and debug if I didn't find it by just a short look.
