To understand how for. T do. B end. works you have to go to the specific
description for for., not just how T and B blocks work in general. The
code between for. and do. is a T block in the sense that that code will not
be considered as the result of the function. ("The final result is the
result of the last sentence executed that was not in a T block, ...")
