[Wikitech-l] is_callable( $realFunction )

Hey,

I just got a bug report for the following code:

$realFunction = array( 'OutputPage', 'includeJQuery' ); if ( is_callable( $realFunction ) ) { //... }

The user is getting a strict warning because the includeJQuery is not static. Now I'm wondering why this check is done in such an odd way to begin with, this would be a lot simpler:

if ( method_exists( $wgOut, 'includeJQuery' ) ) { ... }

I vaguely remember someone saying something about this beeing needed for HipHop, but can't find this documented anywhere where such checks are used. So can someone enlighten me here? :)

Cheers
