I have some code with an anonymous sub that uses __ANON__ to set the sub
name in logging and error messages (a semi-documented trick) like:
sub {
local *__ANON__ = "subname"; # name the anon sub
[...]
warn *__ANON__,": ...\n";
The problem comes about with the warn call that wants to reference
__ANON__. If __ANON__ is used by itself, it produces a bareword warning.
If it is used as a glob (either *__ANON__ or *{__ANON__}), it works, but
produces output prefixed with "*", which seems to suggest it isn't
really being interpreted as a glob.
While the real code is going to end up using a Log::Log4perl method
instead of warn (which internally uses caller()), making this moot, I'm
curious to know what the correct syntax is here.
