in thread Tk::Error: Failed to AUTOLOAD `TK::Widget::EnterFocus'

Your Tk version is more than 11 years old: Changes, and your Perl is 10 years old: perlhist.

It seems like some kind of namespace problem, the program tries to autoload EnterFocus and guesses the namespace incorrectly.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
