I think this doesn't mean we can defined or undef subroutines as well. I don't understand what you're saying here	[reply]

When we execute my code above, the script throws an exception because `&{ 'run' }` violates "strict refs". Khen1950fx explained how to avoid this problem (I appreciate his suggestion). On the other hand, when we comment out `&{ 'run' }`, my script doesn't output error messages. This result shows the following doesn't violate "strict refs": `my $walkable = defined &{ 'walk' }; undef &{ 'walk' };` [download] It seems each line uses symbolic references. I don't understand why this is possible.	[reply] [d/l] [select]

Well , yes, this part I understood when I answered Re^2: undef/defined &{$name} while "strict refs" The answer according to strict is that its an exception made for AUTOLOAD	[reply]
