Is it possible to dynamically load an itcl method?

[zombieZero]

Sorry if this is a simple question, but I just can't figure out how to do it (if there is actually even a way to do it). Here's what I'm trying to do:

Say I have a file:

DUT1.tcl

Within that file, I define a class:

itcl::class DUT1 { etc...

Within that class, I define a method:

public method clearCounters {port args}

Then, I add the method itself:

itcl::body DUT1::clearCounters {port args} { etc...

NOW; I make a change to the clearCounters method; I want to basically reload the method to get the change. If I try to resource DUT1.tcl it will fail because the class DUT1 already exists.

Is there a way to basically reload a method?
