eval "package $package; &$code; 1" or die $@;

I think you're missing a "\" before "$code". But then the code will be called via a code reference, and the contents of the code reference are still in the old package (where they were compiled):

sub run_in_package (&$) { my($code, $package) = @_; eval "package $package; &\$code; 1" or die $@; } run_in_package { showcaller(); } 'foooo'; sub showcaller { warn scalar caller; }

The text of the warning will be "main" (not "foooo").
