Hi,
Not sure what you mean by "scheme code," but I'm just talking about a
simple `for..in` loop. Off-the-cuff:
function createClass(superClass) {
var cls, name, value;
cls = Class.create.apply(Class, arguments);
// Is there a superclass?
if (Object.isFunction(superClass))
{
// Yes, see if it has any statics we should grab
for (name in superClass)
{
if (name !== 'prototype' &&
name !== 'addMethods' &&
// ...there will be several of these...
superClass.hasOwnProperty(name)
)
{
// A static, grab it
cls[name] = superClass[name];
}
}
}
return cls;
}
Something like that.
