Re^2: Can't get rid of: Useless use of private variable in void context

Yes, much more beautiful!
sadly I still got to use perl 5.10 so local *HTEC... is not working

However, the ||= 0 version makes the code much more better and makes me get rid of all the if statements!
I will use it that way!
Thanks a lot!

Cheers!

Tobias

sadly I still got to use perl 5.10 so local HTEC... is not working* Sure it is, it worked since the very first perl5, at least `perl -MData::Dump -e" dd $f={2,{4,{6,8}}}; local *H=$$f{2}{4}; dd\%H" { 2 => { 4 => { 6 => 8 } } } { 6 => 8 }` [download]	[reply] [d/l]

Hey, you are right! :-) Perfect! But there is one thing, I have to remove the `use strict;` else I get a: `Global symbol "%HTEC" requires explicit package name at...` Thanks a lot! Tobias	[reply] [d/l] [select]

There may be some case where removing "`use strict;` is a valid approach, but if so, I'm having a hard time thinking of it (not that I tried very hard -- because `strict` is your friend). Put it back in and find out how to make the hash "legal" (perhaps by declaring it with "`my`"). If you didn't program your executable by toggling in binary, it wasn't really programming!
