[Raleigh-talk] life without use strict

Consider the following code:
1 #!/usr/bin/perl
2
3 #NOPE!#use strict;
4
5 my $var;
6 $var = 1;
7 $var->{key} = '123456789';
8
9 print $var . "\n";
10 print $var->{key} . "\n";
After line 7, does $var hold a hashref, or the number 1? If you turn back
on use strict, you get the following error:
Can't use string ("1") as a HASH ref while "strict refs" in use at
creepy.pl line 7.
So it looks like perl is storing the number 1, but with strict off the
output is:
1
123456789
What's going on here? I'm running perl 5.8.8. It seems like something
should either be a hasref or not. I didn't realize perl would be this
context sensitive, even with strict off.
