I don't like this idea too much, because of the unintuitive consequences when people start factoring out their code into macros: suddenly, the expansion won't happen "at this point", but before the macro, possibly even before some other macro expansions. Explaining this to new users is difficult enough already; and wrapping the requirement in a macro is easy to do for those that know what they are doing. Thanks for fixing the reported issue. Cheers, Ralf
