If you are not using $_ in the local block, this should meet the need to avoid temporary variables, while maintaining readability, and avoiding "do":

my $variable=bless \(local $_=49) ,'Rates::Notification';
As mentioned before, the assignment is necessary to avoid "Modification of a read-only value attempted at ..".

If you are using $_, then the previous recommendations apply, in order to reduce the scope of the local assignment.
