Basically, Ruby is able to do all the crazy mocking stuff because of its mutable type system, and the only way to make the CLR's type-system mutable is to rewrite the IL. To put it in SAT terms:
"rewriting IL" is to "static languages" as "monkey-patching" is to "dynamic languages" =P ~Jimmy > -----Original Message----- > From: ironruby-core-boun...@rubyforge.org [mailto:ironruby-core- > boun...@rubyforge.org] On Behalf Of Ben Hall > Sent: Sunday, January 24, 2010 1:31 PM > To: ironruby-core@rubyforge.org > Subject: Re: [Ironruby-core] Mocking behavior between clr types > > Hi Ivan, > > I was thinking Mono.Cecil first and then the CLR profiling API as I'm pretty > sure that will work.
