[jira] [Commented] (MAHOUT-1726) R-like vector concatenation operator

    [ https://issues.apache.org/jira/browse/MAHOUT-1726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14569984#comment-14569984 ] 

Dmitriy Lyubimov commented on MAHOUT-1726:
------------------------------------------

actually, the cumulative patch lacks variants like 

1.c(b)
or a.c(b,d,...)

i guess this can be filled in later.
