Description

Conditionals like (if), (switch), (try) return their resolved value by assigning it to a reference variable in each branch of execution, and putting this variable after the form. When such a form comes last in a function, we should returnify each branch (prepend a return to the last expression) instead of referencing it and returning the reference.

Research direction

No files or tests are named. Start by tracing how conditional forms such as if, switch, and try are compiled, then find the handling for a form in final function position. Done means each final branch returns its last expression directly instead of assigning it to a reference and returning that reference.
