Oh wise and omniscient monks,

Im trying to understand why this works to import strict into the callers package:

# Foo.pm
package Foo;
sub import {
    strict->import;
}

# script
use Foo;
$yup = 5; # bang! (Global symbol "$yup" requires explicit...)

I know that normally to import package based modules, you can write something like this:

# Foo.pm
package Foo;
sub import {
    my $caller = caller;
    eval "package $caller; use Data::Dumper;";
}

# script
use Foo;
print Dumper(\@ARGV); # $VAR1 = ...

Which makes sense because the use statement thinks it in the callers package. strict is strange because it imports into the lexical scope of the caller, and I thought that would be the block of the import routine in the first example above. So how does it know to enable strict for the callers lexical scope?
