Self-reflection is a purity issue.  Are you worried about obscure bugs
when something else hijacks the name of your function (or module or
class), but your function is still somehow runnable?

Practicality Beats Purity, but purity still has some value.  I will
also note that names are particularly likely to get reused in some
contexts (GUIs, security proxies) where the writer of the original
code can't rely on anything about the runtime environment.

Agreed.
