Possible syntax ideas ``` r # this does not parse f Error: unexpected '{' in "f

Maybe just redefining `return()` is simpler, I guess there would be slightly more overhead in the case where there were no returns in the functions. Another syntax alternative is putting...

One downside to both the approaches with the check right after the arguments is our definition of `?` when _not_ using argufy has to change because the real statements will...

The easiest thing to do is just construct a call to the checking function with whatever is in the body. If it is bare it is directly passed, if it...

Good points, using `withVisible` should allow us to pass on the visibility. The `parent.frame` should be OK, but I the call stack will be affected of course. I don't see...
