> The block part is easy; but is it possible to make it do the expression part? no, unfortunately there's no prototype mechanism for the latter. You can neither easily allow calling a function (which is a special case of the expression part). There was a discussion about this a year ago, I will update a link. UPDATE: see coderefs and (&) prototypes and The & prototype and code references in scalars..
