  Not all that rare.  From my previous example, I did stripped versions, and
on a 32-bit system:

The compiled-stripped version of enum.lua (enums.o) is larger than the
original source, but for the rest, they're marginally smaller.  Now, on to
the 64-bit versions:

-rw-r--r-- 1 spc spc  1072 2014-06-18 11:57 utils.o

  There, both compiler versions are larger, athough the stripped versions
are only a bit larger.
