What’s the reason that script/server loads your .irbrc for every page  
request? It seems dangerous to me for a couple of reasons, one is that  
it might make your development environment drastically different than  
your production environment (especially if you use GuessMethod or any  
other method\_missing/const\_missing hacks in irb). And it can fill your  
server terminal window with tons of unrelated-to-your-app error  
messages about undefined methods on nil if you do something like  
configure an irb prompt (with IRB.conf[:PROMPT]).

I’ve resorted to wrapping my entire irbrc in unless $0 == ‘script/  
server’ … end, but that seems like an inelegant solution.

So, why does it do it?

Thanks,
