I don't see how that could possibly work, since you are declaring the value
of $hash{1} to be $domain, which has not been initialized. You are
declaring $hash{1} to be the VALUE of $domain. When you change $domain
later, this won't update your hash retroactively. Maybe this is just a typo
in your post?

Subject: Population of variables in hash values...
Hey All,
Is there an easy way to have variables in the value of a hash that are
not populated until the value of the hash is used... for example:
my($domain);
my(%hash) = (
1 => "$domain"
);
print_domain("test.com");
sub print_domain() {
my($domain) = @_;
print $hash{'1'};
}
What ends up happening is the printing of a null string (I understand
why since $domain didn't contain a value when the hash was initially
populated)... however what I would like to have happen is the $domain
value of the hash be populated when it is called in the sub, thus
printing "test.com". I've tried references in the hash (i.e. 1 =>
"\$domain") however then I just received the SCALAR(memaddr) as output.
Any suggestions that might help point me in the right direction would be
greatly appreciated.
Thanks,
Tim.
