No.  First of all, the script can be an external script, so innerText 
doesn't do the right thing.

That's the thing.  The privileged bit involves things that make it very 
difficult to transport exceptions across it correctly, especially if the 
caller of execute() is not in the same window as the script itself.  At 
least in Gecko.
