I had to do the same thing when revising the MC IDE. As Mark said, the 
script won't compile if there is an unknown property anywhere in it. But 
"do" statements are not compiled when the script is saved, they are only 
compiled when they need to be run during script execution. So that's how 
we sneak it past the earlier engines -- hide it in a "do" statement 
which doesn't get compiled until it is needed.
