The word is operator. If it's not an operator what is it a puppy? It is not a puppy, it is a "dereferencing symbol" https://perldoc.perl.org/perlref.html "which sub is rAising invalid command?" It is the Tkx::after command that is raising invalid command when its time has arrived to actually call its argument. "What command where?"The command is the one created by $tkxfsr->{after}{$afterid}{sub}=sub{ ...}; since the code address match. "What is undefinex at time of sub call? " Nothing is actually undefined at the time of the call, but for some reason the execution part of Tkx:after thinks it is.
