4726 [yashi yashi.] indeed. :)

4702 [ms iastate.e] (1) A top-level method gets appended to the Object class and made private,
4703 [Dave thomase] It still raises the exception, it's just that the hierarchy changed

4708 [Dave thomase] The latest eval.rb is already fixed. It has

4713 [decoux moulo] Perhaps this case ?

+ 4740 [schneiker ju] I guess I didn't read the docs carefully enough. The reason I didn't mention
+ 4743 [Dave thomase] my @a = split(/,? */, "1.2, 3.4, 5.6/");
+ 4747 [decoux moulo] There is a difference between perl and ruby.
+ 4748 [Dave thomase] This would seem to be a problem with Perl ;-) Try is with a zero
+ 4750 [decoux moulo] a scan() is more like a //g in perl
+ 4751 [Dave thomase] You're right - I should have had a /g on the Perl example.
+ 4752 [decoux moulo] Yes but perl and ruby don't have the same notion of zero-length match
+ 4754 [Dave thomase] d'accord. That's true, but kind of orthogonal to the point that Conrad

4799 [nahi keynaut] No, AFAIK. Word 'official' did not make sense to me...
