"our" is one of the best improvements in perl, because one has not to fiddle around anymore with different scoping rules for "my" and "vars" and allows consistent declarations! That's orthogonality (almost) at it's best! Unfortunately the features are ignored by the wide public, thinking it's just a a new name for an old mechanism.

Anyway there are some traps when our is used with special vars, for instance something like  our $\="\n"; will make B::Deparse fail ... 

lanx:~$ perl -MO=Deparse perl/myour.pl
While deparsing perl/myour.pl near line 3,
Unexpected our($\)
CHECK failed--call queue aborted.

lanx@:~$ perl -version

This is perl, v5.8.8 ...

nice for obfuscation ; )

> In any case this is an example of why it is better to have a precise understanding of how features work rather than having a vague impression that is going to mostly work, most of the time.

FULL ACK! Especially because really understanding "our" implies really understanding "my".
