S28 update?

Is there any chance someone could have a look at the stuff in the section labelled "Old stuff for p5/p6 comparison" of S28, and give me some info on what's going on with them? In particular, I want to know: - What's going to replace $^V / $PERL_VERSION / $] -- is it $?PERL ? - Wh

Re: @*INPLACE_AUTOSPLIT_FIELDS

In answer to this, Larry put something in the spec that says that @F is replaced with @_ Now I'm happy :). - | Name: Tim Nelson | Because the Creator is,| | E-mail: wayl...@wayland.id.au| I

S28 -- more profusion of confusion on my part :)

Hi. I wrote a variable finding program. The output is below for those interested (yes, it relies on ack), but the questions the output raises are: - Does the $?TABSTOP have a special meaning, or is it just an example like $?FOO is in so many places? - Should those @?ROUTIN

Exceptions question

S04 says: Because the contextual variable C<$!> contains all exceptions collected in the current lexical scope, saying C will throw all exceptions, whether they were handled or not. A bare C/C takes C<$!> as the default argument. Does this mean that $! is a container of some sor

Masak's S29 list

Here's my comments on Carl Masak's S29 list. Note that some of the things that say that they're "now in" something still need a lot of work. # Range objects have .from, .to, .min, .max and .minmax methods Now in S32/Containers.pod # .contains on Hash and Array Where's this from? #

More S29/S32 Masak ideas

Apologies to Carl Masak for writing his name in ASCII. # context(). Added to S29, but I still don't know where these should go. Maybe on Block? # .wrap, .unwrap and .assuming. Added to S32/Callable. # callsame, callwith, nextsame, nextwith, lastcall. Didn't know where t
