Update: See my reply below for a better explanation of what happened.

Hi, I inadvertently tried to execute a file named ?1. What surprised me was the output. 

$ ?1

I guess I could make this a Perl question by executing it thru Perl IPC, but can someone help me make sense of what that output is? A bug ? Thanks.
