open()

In a reply by A. Guzman I found the following paragraph:
==

Please be careful with your open(), you will have problems if you do not
use a multiple argument open(), ....
And you shouldn't use bare-word filehandles.

==
So far I used quite successfully bare-word filehandles except in the cases where
I wanted to pass the filehandle to a subroutine or store it somewhere.
Why should one separate the ">" etc. from the file name?

Thanks.
