Hi Georges,
Are you using Boo trunk or Boo 0.9.1 (the version number is still the same, Rodrigo feel free to "bin update" ;-) ) ? If confirmed with trunk can you post the -vvv output here.
I'm using one version between the latest stable and the trunk version.
But looking at the Moq code, it looks like the setup method needs a
lambda expression as parameter. Exists in Boo any way to express
lambda expressios ? If i'm not mistaken they aren't the samething as
callables/delegates.
Thx

What is the error exactly?
Lambdas in C# are sort of interesting in that they can be used to express
two different types, Delegates or Expressions. I'm not sure how it works in
Boo, but if it can't compile a lambda into an expression that might explain
your error. For example in C#:
But will compile to different types. I'm guessing the Moq framework is using
the Expression<T, bool>? In that case you get an expression tree which you
can look at and query to get all of the inner expressions at runtime and do
reflection and what not. You can also compile it into a delegate on the fly
and execute it. Will boo compile lambdas into Expression<Delegate>? or does
it always build a delegate?

That is the case, Moq expects Expressions and not delegates, because
it introspect the Expression to see if some call to the method defined
in the expression tree was called.
I'm almost sure that Boo doesn't compile a lambda to a Expression, so
it can't be used with Moq :(
