Subject [jira] Commented: (STDCXX-605) [IBM XLC++] errors compiling dynatype.cpp
Date Thu, 13 Dec 2007 00:21:43 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12551167
] 

Martin Sebor commented on STDCXX-605:
-------------------------------------

Looks like you've been able to come up with a clean solution after all -- excellent!

I do have one question about the patch to make sure I understand how it works: do both overloads
of retrieve() need to be const? It seems that the one returning (non-const) T& should
be non-const, no? (And shouldn't the call to the const overload cast the argument to const
T* instead of plain T*?)

Also, there are a few gratuitous whitespace edits in the patch (unnecessarily added newlines)
that should normally be avoided, and a few formatting issues (missing spaces before open parens).
