 Every so often, we get bitten by a random {{{foreach()}}} error due to the
 input not being an array.


 The elegant solution is this:

 {{{
 foreach ( (array) $maybe_array as $foo ) :
 }}}

 The attached patch is just the result of a giant regular expressions
 find/replace:

 {{{
 search: foreach( *)\(( *)\$
 replace: foreach$1( (array) $
 }}}

 this is more proof of concept than anything else.  I'm not getting any
 errors after applying it.  I'd love to banish foreach errors once and for
 all.
