Is there a way to write to a Custom Label via Apex? The online documentation doesn't outright say that you can't, but I'm guessing it's called a 'custom label' rather than a 'custom variable' for a reason.
My naive efforts to do
Label.myLabel = 'foo'; System.Label.myLabel = 'bar';
result in the following error:
"Error: Compile Error: Expression cannot be assigned at line 12 column"
