[jira] [Commented] (ARROW-3686) [Python] Support for masked arrays in to/from numpy

    [ https://issues.apache.org/jira/browse/ARROW-3686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16762839#comment-16762839 ] 

Wes McKinney commented on ARROW-3686:
-------------------------------------

We have a {{mask}} argument to {{pyarrow.array}} already. It would seem reasonable to detect {{ma.MaskedArray}} and grab its mask

> Again, in this PR for vaex: [https://github.com/maartenbreddels/vaex/pull/116] I support masked arrays, it would be nice if this goes into pyarrow. If this approach looks good I could do a PR.
