Re^4: Spotting an empty array as argument

While prototype would normally be a useful thing to try, say can't be prototyped because it supports say FH ..., so a definitive answer can't be obtained from prototype here (assuming the lack of file handle support is acceptable).

> say can't be prototyped because it supports say FH ..., I can't follow, the fact that `say` is internally calling something like `FH->print(@_,"\n")` shouldn't have any consequence on the prototype. Hmmm ... I think what you mean is that this inhibits attempts to override `say` with another implementation, since it needs to act like an indirect method call, but with prototype magic.

the fact that say is internally calling something like FH->print(@_,"\n") shouldn't have any consequence on the prototype. It doesn't. It's the syntax that can't be recreated with a prototype. I think what you mean is that this inhibits attempts to override say with another implementation, Not at all. That's what the comment to which I replied said. I pointed out that's not necessarily relevant since the OP didn't ask to replicate all of `say`'s syntax, and irrelevant parts of `say` can't be recreated using prototypes. It was a nitpick. It is, of course, entirely correct that the relevant behaviour of `say` can't be replicated with a prototype. It just can't be ascertained by the means used by the person to which I replied.
