As it happens DBD::Oracle does use Oracle's precompiler. But it's more of a
hindrance than a help. It basically has to define and implement its own API
which is compiled with Pro*C. Then the rest of the codebase can ignore the
precompiler and use that interface.
Precompilers are really old school. There's not much point to using them
except in legacy applications that need them. They offer no advantage over a
programmatic API, and lots of disadvantages. You have to learn a new language,
you're one step further removed from the resulting code, and heaven help you
if your compiler version doesn't match what the precompiler was tested with.
Nevermind actually trying to use it from another language entirely.
