Re^5: Recover a path from a config file

thanks for that browser. I would still advocate assigning undef to it explicitly though for clarity.

    local $/ = undef; $slurp  = <fh>;
[download]

is in fact the example given in perlsub and I feel with good reason.

Do you write: `my $c = undef;` for all your lexicals? local declares & initialises a new, scoped copy of a variable.

Yes but because it's a copy of a global variable it creates expectations of inheritance that "my" doesn't. The documentation has changed over time owing to confusion it caused about what local is or isn't supposed to do. The latest version has at least as much warning about what it isn't than clarity about what it is. Your own definition looks good to me and I'd like to see it reflected in perldoc just as clearly.
