ruby safe import in production code

[gnecula]

I do not understand this safe import. Does this allow "if bond.testing" ? Why do we need the DUMMY_BOND name, can't we just assign to bond directly?

begin
require 'bond'
rescue LoadError
module BondTargetable
DUMMY_BOND = Class.new { def method_missing(meth, *args); end }.new
def self.included(base); base.extend(BondTargetable); end
def bond; DUMMY_BOND; end
end
end

It doesn't allow for 'if bond.testing' at the moment; good point. I created
DUMMY_BOND so that it isn't creating and instantiating a new class on each
call to Bond, since this is supposed to be for production code, but it's
definitely not ideal. I was hoping to discuss some of the implementation
details with you when we met these week because there are some oddities
that I was hoping to get your opinion on.
