in reply to An eighth use of local

My most common use of local deals with recursive method calls:

sub foo { my $self = shift; local $self->{some_val} = $self->get_val; # do a bunch of stuff $self->foo; }

This seems strange, but I do find this useful at times. It allows me to temporarily overwrite a value which needs to be preserved for a given stack frame.

Cheers,
