```{index} single: numify; File::Temp function ``` ```{index} single: File::Temp::numify; Perl function ``` # numify Overload handler for `0+` — numify a `File::Temp` object to its reference address. ## Synopsis ```perl my $tmp = File::Temp->new; print 0 + $tmp, "\n"; # the refaddr $tmp == $other_handle # compares by identity ``` ## What you get back The integer refaddr of the underlying reference — the same value `Scalar::Util::refaddr` would return. ## Differences from upstream Fully compatible with upstream `File::Temp` 0.2312. ## See also - `STRINGIFY` — companion overload used for string contexts.
