The reason why there is an encoding pragma, and why it's per file, is 
because text editors deal with one encoding per file. Doing something 
like an encoding pragma e.g. on a block basis would not work well 
together with editors.

I agree with Charles and others that a file-based directive isn't a good 
idea for frozen/fixed strings.

 From a more general perspective, it feels to me that introducing all 
these frozen options will increase performance, but at the cost of 
programmer effort. That would be the case also e.g. for something like 
type hints,..., but that's not Ruby style.

Regards,    Martin.

and it's also the express purpose of refinements.
