Interesting talk on Python vs. Ruby and how he would like Python to have just a bit more syntactic flexibility.

If it was Perl [1], I doubt it. Because line numbers are reported, and
if that doesn't help you, you can annotate anonymous functions with a
nick name using

local *__ANON__ = 'nice name';

Finding an issue, and not looking for a solution is not called becoming
enlightened ;-)


~$ perl -e '
use Carp;

my $anon = sub { local *__ANON__ = "hello, world"; croak "oops"; };
$anon->();
'

oops at -e line 4
	main::hello, world() called at -e line 5

As you can see, and a line number is generated, and the nice name is
shown.

If you generate anonymouse functions on the fly based on parameters, you
can encode this into the nice name, of course.

Sadly, often bold statements about a language are made in ignorance.


[1] perl is the program that executes Perl programs ;-).
