Re: What the @#%* lost again!

READ isn't a reserved word in Perl, but read is. But it's fine to use filehandles with the same name as (some) all-caps words with a special meaning, as shown below:

#!/usr/bin/perl

use strict;
use warnings;

open BEGIN, "/etc/passwd" or die;
print while <BEGIN>;
__END__

The program compiles and runs without problems.

Thanks for letting me know that Abigail. I didn't realize you could use reserved words in filehandles. I guess it's just more of a recommendation that you don't use them. Thanks again.	[reply]

Well, I carefully worded it "all-caps words with a special meaning". `BEGIN` isn't a reserved word. However, you can use reserved words as file handles, as long as you quote them when appropriate: `#!/usr/bin/perl use strict; use warnings; open print => "/etc/passwd" or die; print while <print>; __END__` [download] If you replace the `=>` with a comma, the code above won't compile.
