 Love 'em or hate 'em, WordPress uses lots of constants.  As a result, this
 pattern is all over core and plugins, and occasionally themes:

 `if ( defined( 'CONSTANT_NAME' ) && CONSTANT_NAME )`

 Right now on trunk, it's used 57 times (excluding 2 in Akismet).

 {{{
 ~/code/wptrunk $ ack "defined\( ?('|\")([^'\"]+)\1 ?\) \&\& \2" -h
 --ignore-dir=wp-content/plugins/ | wc -l
       57
 }}}

 How about a new function to make that verbose logic a little bit less
 repetitive.

 {{{
 function wp_constant( $constant ) {
         return defined( $constant ) && constant( $constant );
 }
 }}}
