[jira] [Comment Edited] (ARROW-13943) [Python][C++] Hide hash_* functions from pyarrow.compute

    [ https://issues.apache.org/jira/browse/ARROW-13943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17438825#comment-17438825 ]

Is the  {{Function::kind()}} available to pyarrow? It seems that comparing that to {{Function::HASH_AGGREGATE}} might be a way to filter those

> These functions have been specifically forbidden from being called by python.  An attempt to do so will yield:
> pyarrow.lib.ArrowNotImplementedError: Direct execution of HASH_AGGREGATE functions
> The functions should not show up in pc.list_functions at all and pc.get_function should return None if given 'hash_sum'.  Perhaps they could be stored in a different registry?  Or, since we are special casing them anyways, special case them in some way they can be hidden?
