It helps to imagine that these functions are 100 lines long instead of 1
line long.
The programmer assumes that a value is being returned by foo(), because
of the return(1). The programmer also assumes that a value is being
returned by baz(), because of the return(bar()).
It's not that something can go wrong, its just the program is not doing
what the programmer expects. Nothing goes wrong when there is
unreachable code, but gcc still emits a warning when it detects
unreachable code.
