Comment (by TimothyBlynJacobs):

 In most cases it would be fine, but it'd be a problem with functions that
 use a variable number of arguments.

 I'd imagine something like this. Though you're right that'd get clunky as
 well. Especially for a object function name pair.

 {{{#!php
 $arg['validate_callback'] = array( 'myfunction', 1 );
 }}}
