Can I set a module context for a block?

Ruby
1

I’d really like to be able to inject the ‘include Bob’ statement in the
create method of Bob:

module Bob
def method_missing(name, *params)
puts “missing: #{name}”
end
def self.create(name)
yield if block_given?
puts name
end
end

Bob::create(‘hi’) do
include Bob
ldstr
ldc_i4_0
end

Is there a way that I can avoid include Bob in my block?

Thanks
-John

def self.create(name)
module_eval do
yield
end if block_given?
puts name
end

Thanks, Robert! Your solution neatly solves my next problem, which was
how
to declare a private context for the evaluation of the method_missing
elements.

Cheers,

Bah, never mind, I thought I’d removed the ‘include Bob’ when I tested,
but I hadn’t, heh.
