This is standard operating procedure when loading a dialect, or just code you dont want evaluated yet. If you want the code evaluated, use 'do, if you dont use 'load.

This is because when you 'do a file, your really doing ('do'ing?) a string. REBOL code is normally not evaluated in a string until the REBOL header is found. I suppose /plain refinement would be nice in certain instances, but 'do 'load really isn't so bad. Check out 'save/header. It tackles the problem from the right end by adding a header to code you might want to leave around for later. Have fun, --Ryan
