But in interpreted execution, the macro is expanded each time the macro call runs, and this means a new object is constructed each time. --- I think this is pretty clear -- it's guarded by "if", but it doesn't claim that compilation will always expand the macro. So I think this should be sufficient, and I'm closing this bug report. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
