There's actually (at least) two versions of GP's comment - unsafe code/data, what you appear to be referring to:

  rm -rf $FOO/*

And typos, which is what I first thought of upon reading it:

  rm -rf . /*

Well, "us" except Unix and Unix-like developers, where "rm -rf /*" still works like it always did, unless your rm added --no-preserve-root or some similar ugly hack.
