fc activates the verbose mode to print the commands as they're read by the parser and uses unwind_protect_int to restore it.
This is a good idea but there are a few problems with it: 1. it prints the DEBUG trap, which I didn't expect 2. it's impossible to use fc to turn on/off the verbose mode ( well, you can, but it's lost as soon as the command ends ) Is it possible to print the commands without activating that mode? --- xoxo iza
