If there is a `sub foo` that uses the above method of detecting when it is called in void context so that it can do less work; then that would be a reason the caller of `sub foo` (docdurdee) might want to enforce void context on it.	[reply] [d/l] [select]

But doesn't just calling `foo()` in void context `foo();` enforce void context upon the invocation of `foo()`? What need for anything else? Is it ever possible to get a value directly returned from a subroutine invoked in void context, whether "enforced" or "natural" (as in the example above)? (Of course, it's always possible to indirectly return values from subroutines invoked in void context.) Give a man a fish: `<%-(-(-(-<`	[reply] [d/l] [select]

What need for anything else? True, but it can still happen by accident that a sub is executed in non-void context when the programmer wanted it in void context, as shown above in `sub calls_it_1`. Also docdurdee mentioned a REPL, so my guess would be that the REPL puts every line entered at the prompt into some non-void context.	[reply] [d/l]
