Why not?  A function definition usually has some specific keywords in
it.  It is true that someone could have obfuscated the code which
generates a function to the degree that it would be infeasible to
recognize, but we don't need to support such arbitrary measures, we
only need to support what's really being used.  IOW, "reliably"
doesn't need to mean with 110% reliability.
