The '()' syntax is obviously closer to describing what you want (ie,
discard the return value), whereas the 'pop' disguises things quite a
bit.

If you use 'pop', you also need to know how many return values to pop
from the stack. Using '()' is much more convenient and gives you the
opportunity to assign some of the return values. For example,
    variable mode;
    (mode,) = what_mode()
