CSET库中存在语法错误

我正在使用 CSET

自 cset_production.js :

游猎

SyntaxError: Parse error
(line 255)

CSET=function(){
// ...
var g=this
return {import:function(prefix,object){object=object||g
 var i,l,e,es=           // SyntaxError: Parse error (line 255)
 [['fromChar',fC]
 ,['fromInt',fI]
 ,['universe',U]
 ,['nil',nil]
 ,['empty',empty]
 ,['singleton',one]
 ,['fromIntRange',fIR]
 ,['fromCharRange',fCR]
 ,['fromUnicodeGeneralCategory',fGC]
 ,['complement',comp]
 ,['fromList',fL]
 ,['fromString',fS]
 ,['member',member]
 ,['difference',diff]
 ,['union',union]
 ,['intersection',inter]
 ,['toRegex',reCC]
 ,['show',show]
 ]
 for(i=0,l=es.length;i<l,e=es[i];i++)
  object[(prefix||'')+e[0]]=e[1]}}
}();

Safari语法错误的原因是什么?我该怎么做才能纠正这个问题?
