I have created a bug report to avoid this whole pair of threads to be lost in the dusts of time:
http://d.puremagic.com/issues/show_bug.cgi?id=5212

Feel free to add a note about your ensureHeaped() idea at the end of that enhancement request :-)

(To that enhancement request I have not added my idea of the @onheap attribute because I think it's too much complex to implement according to the design style of the D compiler).
