[jira] [Commented] (LANG-701) VarArgs Join

["Matt Benson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13037429#comment-13037429 ] 

Matt Benson commented on LANG-701:
----------------------------------

I would support the addition of new methods to permit varargs usage with StringUtils operations that were available in previous versions of [lang] but whose argument order didn't lend itself to a smooth varargs transition; however IMO these should be _new_, not overloaded methods, i.e. have new names.  I would recommend we use idiom patterns like {{joinDelimitedBy(delim, args...)}}, for this example.

> I missed the functionality of joining strings with the space separator in one line. BTW, why space ' ' not a constant field anywhere?
