Summer of 1997 or 1998. Fresh college grad. Pre-release of some patch level of Tcl 8 (which introduced byte compilation, making it slightly more plausible there would be a compiler/interpreter/language bug).
Yeah. I grew up typing on computer keyboards so I couldn't believe the explanation. Some of the older employees were much more understanding as they learned to type on typewriters that literally didn't have a 1 key at all.
