[=] captures slaveId by value (copy) so it won't be invalid? But after when to use lambdas, I think this is a good point and we should establish some best practices. Google style guide has these guidelines: https://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Lambda_expressions Avoiding default captures is one of them; limiting the length of lambdas is another. We should document these, at least reference Google's. And how about lambdas that simply call another method vs. bind? :) - Jiang Yan ----------------------------------------------------------- This is an automatically generated e-mail.
