iuembed and eval statements

I was looking at the iuembed script and noticed you use eval statements in a few places. These are expensive and can be handled differently. I've substituted the eval statements with an alternate method. We've been using this for about 6 months without error.

Code with eval statements (starting at line 34):

if (typeof(o[props[i]])=="unknown"){
eval("o.set"+props[i]+"=function(i,v){this."+props[i]+"(i)=v;};");
eval("o.get"+props[i]+"=function(i){return this."+props[i]+"(i);};");
}
else{
eval("o.set"+props[i]+"=function(v){this."+props[i]+"=v};");
eval("o.get"+props[i]+"=function(){return this."+props[i]+"};");
}
}
if (hasPaneItemApiElements){
eval("o.setPaneItemDesign = function(Pane, Index, Value){this.PaneItemDesign(Pane, Index) = Value;};");
eval("o.getPaneItemDesign = function(Pane, Index){return this.PaneItemDesign(Pane, Index);};");
eval("o.getPaneItemSelected = function(Pane, Index){return this.PaneItemSelected(Pane, Index);};");
eval("o.setPaneItemEnabled = function(Pane, Index, Value){this.PaneItemEnabled(Pane, Index) = Value;};");
eval("o.getPaneItemEnabled = function(Pane, Index){return this.PaneItemEnabled(Pane, Index);};");
}

Alternate to eval statements:

if (typeof(o[props[i]])=="unknown"){
o['set'+props[i]] = function(i,v){this[props[i]](i)=v;};
o['get'+props[i]] = function(i){return this[props[i]](i);};
}
else{
o['set'+props[i]] = function(v){this[props[i]]=v;};
o['get'+props[i]] = function(){return this[props[i]];};
}
}
if (hasPaneItemApiElements){
o.setPaneItemDesign = function(Pane, Index, Value){this.PaneItemDesign(Pane, Index) = Value;};
o.getPaneItemDesign = function(Pane, Index){return this.PaneItemDesign(Pane, Index);};
o.getPaneItemSelected = function(Pane, Index){return this.PaneItemSelected(Pane, Index);};
o.setPaneItemEnabled = function(Pane, Index, Value){this.PaneItemEnabled(Pane, Index) = Value;};
o.getPaneItemEnabled = function(Pane, Index){return this.PaneItemEnabled(Pane, Index);};
}
}
