Re^2: Inspecting the name of a variable

Well ... RTFM doesn't explain anything. =)

localized variables are propagated into any called subs.

apparently PadWalker is missing a pad to investigate or should extend it's documentation.

UPDATE: ... well only if aliases have a pad...

UPDATE: yes it's because of the aliasing:

our $orig=666;
 
for our $x (42,$orig) {
  say $bar,our_name($bar);
  say $x,our_name($x);
}

10$bar
42
10$bar
666$orig

Hello I found Data::Dumper::Names with this thread . In this manual of Data::Dumper::Names, there is "Unknown Variables" section. "Unknown Variables" section seems to me having some relation with your case... not printing name "$x". update: Sorry if I am looking into wrong direction.	[reply]

Thats where I started, but if you look into Ovid's code you will see that he's only inspecting lexical variables. Cheers Rolf	[reply]

I saw it. It used the same module, PadWalker. With -d debug, when I type V at for loop, I see "$x = 42" in the list. It seems there is some way for printing variable names... I know nothing for perlguts,and don't understand what is Alias here ... Hope you get some hints from superior monks. regrads.	[reply]
