Subject [jira] [Commented] (MESOS-2780) Non-POD static variables
Date Mon, 01 Jun 2015 03:55:17 GMT

    [ https://issues.apache.org/jira/browse/MESOS-2780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14566918#comment-14566918
] 

Paul Brett commented on MESOS-2780:
-----------------------------------

I agree Michael.  We should aim over time to convert Duration, Bytes etc to constexpr and
replace std::string with either const char[] or inline const functions.
