Invoking a static method

Is it possible to invoke a static method on a class within an expression. If
so, how?

For example:

#set($arg = "an argument")
#set($o = MyClass.getInstance($arg))
	.
	.
	.


Thanks

context.put("MyClass", new MyClass())
#set($arg = "an argument")
#set($o = $MyClass.getInstance($arg))

In other words, any object in the context is available as a $variable.
Methods on that object can be static.

Note: Your design, IMHO, is breaking MVC. Instantiating objects for the
purpose of use within the template is bad.
