Re^2: my $x = <expr>; vs my $x; $x = <expr>;

I'd write that as

my $x = do {
    open my $fh, '<', '/path/to/foo.file' or die $!
    <$fh>;
};

Note that $fh is auto-closed due to falling out of scope.

Update: the last line was not meant to be $x = <$fh> of course.

Makeshifts last the longest.

You can't use $x in the same statement as you declare it. Your second use of $x is global. The last line in the block should be just `scalar <$fh>` The PerlMonk `tr///` Advocate	[reply] [d/l]

That was just a mistake. Thanks for catching it. scalar is not necessary here, btw, because `my $x =` already provides scalar context. Makeshifts last the longest.	[reply]
