Re: *FOO{THING} syntax used on a lexical variable

The trick is that the *FOO{THING} syntax works on typeglobs. Package variables are in typeglobs. But typeglobs need not be package variables.

My comment might make more sense if you go back to how we did that with Perl 5.005.

use strict;
use warnings;
my $fh = do {local *FOO};
open $fh, "somefile";
my $sc = *$fh{IO};

print <$sc>;

Is it less surprising now?

`FOO{THING}` syntax works on typeglobs* Ah, that's what I was missing. I knew there was a simple explanation! Thanks for your reply. For further reinforcement of your point: `$ perl -le 'open my $fh, "file"; print $fh;' GLOB(0x814cc20)` [download] And to show some symmetry with the package variable variety of typeglob: `open FOO, "file"; print ref \FOO; # prints GLOB open my $fh, "file"; print ref \$fh; # prints GLOB` [download]	[reply] [d/l] [select]

And to show some symmetry with the package variable variety of typeglob:

open FOO,    "file"; print ref \*FOO; # prints GLOB
open my $fh, "file"; print ref \*$fh; # prints GLOB
