Angle_brackets don't work that way.

They do.

++ for your reply, JavaFan because I was misreading this (from the glob doc you cited): `Note that "glob" splits its arguments on whitespace and treats each segment as separate pattern. As such, "glob(".c .h")" matches all files with a .c or .h extension. The expression "glob(".* ")" matchs all files in the current working directory.` [download] Nothing there bars this: `#!/usr/bin/perl use Modern::Perl; my @arr = glob("."); for my $line(@arr) { say $line; }` [download] Also, as noted by Corion, perlop is relevant. If what the angle brackets contain is a simple scalar variable (e.g., +<$foo>), then that variable contains the name of the filehandle to in +put from, or its typeglob, or a reference to the same. For example: $fh = \STDIN; $line = <$fh>; If what's within the angle brackets is neither a filehandle nor a simp +le scalar variable containing a filehandle name, typeglob, or typeglo +b reference, it is interpreted as a filename pattern to be globbed, a +nd either a list of filenames or the next filename in the list is ret +urned, depending on context. [download] Above blockquote added as an update, for future readers TY, both!	[reply] [d/l] [select]

Note that "glob" splits its arguments on whitespace and treats
each segment as separate pattern. As such, "glob("*.c *.h")"
matches all files with a .c or .h extension. The expression
"glob(".* *")" matchs all files in the current working
directory.

Nothing there bars this:

#!/usr/bin/perl
use Modern::Perl;

my @arr = glob("*.*");

for my $line(@arr) {
    say $line;
}

Also, as noted by Corion, perlop is relevant.

If what the angle brackets contain is a simple scalar variable (e.g., 
+<$foo>), then that variable contains the name of the filehandle to in
+put from, or its typeglob, or a reference to the same. For example:

    $fh = \*STDIN;
    $line = <$fh>;

If what's within the angle brackets is neither a filehandle nor a simp
+le scalar variable containing a filehandle name, typeglob, or typeglo
+b reference, it is interpreted as a filename pattern to be globbed, a
+nd either a list of filenames or the next filename in the list is ret
+urned, depending on context.
