I agree that it makes sense to support this on the long run. However, for 
the short run, I think using eval() is sufficient.

If people feel strongly about this, my proposal would be to use sicking's 
idea of just allowing data: URLs. Specifically, making step 3 of the 
Worker() constructor (not SharedWorker) allow data: URLs as a special 
case. That's an easy thing to do, and it's not like we'll ever use data: 
URLs in this context for something else.

That wouldn't have quite the right semantics -- they'd be evaluated in the 
content of the original script (or in a blank execution context, dependeng 
on how we defined it), and then their return value would be executed... 
that's one level of indirection too far.
