Simple in PL/I, although it turns out there is more overhead than you’d
think, particularly if foo and bar have different return types. I used
multiple entries extensively in the Iron Spring PL/I compiler, but it turns
out the “package” construct (once I implemented it) is much cleaner.
Multiple entries is also error-prone if the entries have different
parameters.
