in thread Help needed understanding global variables in Perl

A clarification on the following point.
The closest thing to a global variable in perl is a variable that lives in main::'s symbol table. This is because whenever a variable is referred it is always looked for in main::. But this is only a last resort,

This is not true. If you are not in main:: it will not look in main for a variable unless you use our $var and then it's still only I belive in the current lexical scope.

# Prints nothing. perl -e '$var = 'value';package FOO; print $var' #prints "value" perl -e 'our $var = 'value';package FOO; print $var' #prints "value" perl -e '$var = 'value';package FOO; print $main::var'
