Look at your original code: it's impossible to figure out what it's
doing or whether it's doing it correctly. "Opaque" in this context
means that you can't grok the code without external help. This is a
code smell, and a strong indication that you're "fiddling" in stuff
way lower level than you normally want to be working with. It's
usable, but it's dirty and leaves everything up to you (do you know
for sure, for instance, if this is backward compatible?
Cross-platform?), and that makes it comparable to depending on an
external program.
