Try if (!(@array[0] | @array[1])) instead

Don't, for the reason Marshall++ explained. Micro-optimising code to avoid typing a few characters does not improve performance, and makes maintenance a nightmare (if overused).

Also, your code assumes integers, right? I would have to look up the binary representation(s) of a float 0.0 to see if all bits are 0 there. If not, this probably won't work, resulting once again in wrong results (false negatives, in this case). Maybe floats depend on the CPU and / or math emulation library used, so the result would also depend on the machine it is running on. No, thanks. I prefer code that does not make me think about such issues.

For two or three elements, explicitly compare the elements. For more, see my generalised posting.

Playing golf is a completely different story, but then, the array's name would not be five letters long.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
