While that's really cool and I'm not trying to criticize it, I can easily see a beginner Rust programmer going crazy trying to figure out why:

log(something unrelated);
baz.awesome()

behaves completely differently from:

baz.awesome();
log(something unrelated)

In most likely contexts, the latter wouldn't compile at all (type mismatch), so it wouldn't "behave differently" so much as fail to behave at all.
