Thanks, good to know. That was my impression from looking at the code,
but wanted to make sure.

Thanks, that was exactly the answer I was hoping for :)

I know; that's why I mentioned "initialized" was probably the wrong
term to use. What I meant was that at some point in time, there would

Shared DynamicSites don't get initialized for each specific class/object
and method combination. A shared DynamicSite applies to all invocations
of a method like to_int. The DLR validates the context in which the
invocation occurred and then invokes the dynamic site's target (a
delegate) for

*Sigh*; I'm an idiot; that happens for not looking again to see I was
really referring to RubySites.RespondTo() which uses yet another
shared dynamic site. The overall question still stands, th

First of all, thanks for answering. I'm aware of Martin's blog and
it's a very nice resource, but honestly, the details still seem a bit
hazy to me. In particular:

Hi everyone,
I was watching yesterday's John Lam's Lang.NET presentation on
IronRuby (Great presentation, btw, really enjoyed it), and it was
pretty informative (to me, at least). Besides that, I've been looking
at the IronRuby and DLR code trying to become more familiar with how
everything fits
