Is there some kind of package out there that would allow me to develop  
in ruby 1.8 while avoiding incompatibility with 1.9? Something that for  
example would:  
define String#lines  
warn me when I use String#to\_a  
define Kernel#funcall  
warn me when I use Kernel#send on a private method  
…etc

That would be quite useful.

Austin Z. and I were talking a while ago about how it’d be cool  
to have an option like:

ruby --warn1.9

As far as I know, such initiatives haven’t taken place yet, but they’d  
be quite welcome. I want to start working on 1.9 compatibility for  
some of my projects in the next couple months, to be an ‘early  
adopter’.

1.9 doesn’t sound API-stable enough to start thinking about it yet,  
IMHO.

It is scheduled to be released in December. It will need to slow down  
soon enough.
