a function supplied as a bare symbol, or an expression


if x is a function, then the the same function with a new parent environment, package:tfautograph:ag_mask, which is the autograph mask that contains implementations of R control flow primitives that are capable of handling tensorflow tensors. The parent of the package:tfautograph:ag_mask in turn is the original environment of x.

if x is an expression, then that expression is evaluated in a special environment with the autograph mask ag_mask active. If the result of that expression included local assignment or modifications of variables, (for example, via <-), those modified variables are then exported into the current frame. The return value of the expression is then returned.
