++ 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.

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.

Above blockquote added as an update, for future readers

TY, both!
