fix $foo ~~ /re/, autoref and forbid anything not permitted
The "Smart Match 3" patch removed conversion of:
$foo ~~ /bar/
to:
$foo ~~ qr/bar/
which this change reinstates.
Also this reinstates auto-reffing of the left-hand argument so that
code like:
@foo ~~ \&bar
will call bar(\@foo).
Unfortunately this can lead to:
@foo ~~ "".\@foo
matching, since the left is auto-reffed, then stringified for comparison
with the string on the right.
Additionally, we forbid:
$foo ~~ @bar # compile-time
$foo ~~ %bar # compile-time
$foo ~~ @bar[0.1] # compile-time
$foo ~~ @bar{0.1} # compile-time
$foo ~~ $otherref # run-time, disallow any unblessed reference not
# a code or regexp

add experimental smart-matching against numbers
This causes some tests to fail because $foo ~~ /bar/ is currently
broken and is treated as $foo == ($_ =~ /bar/)

New whirled order for givwhen/last/next
given now responds to last and next.
break only breaks out of given, and does not complain about an
inner foreach.
when and default do an implicit regular next, not a âspecialâ next
that only breaks out of foreach() and given.

toke.c: use goto to reduce repetitition
I couldnât think of a name for the label that didnât just repeat what
the code was doing (increment_lex_allbrackets_and_set_PL_expect), so I
gave it an arbitrary short name.

Smart Match 3â¢
I was persuaded by Smylersâ argument concerning string equivalence:
<20120905143040.gz1...@stripey.com>
But it is not too late for me to be overruled since this is not in
blead yet.
The list is:
RHS type
1. undef
2. ~~ overloading
3. reftype eq CODE
4. reftype eq REGEXP
5. fall back to eq
One question still remains: Should undef ~~ "string" give a warning?
Currently it doesnât, but neither does it call eq overloading on the
RHS if we actually have undef ~~ $overloaded_object_without_smartmatch.
This cannot be merged until we solve the fact that smart match
is used in:
cpan/autodie/lib/Fatal.pm
cpan/autodie/t/exceptions.t
This does not deal with loop controls yet, just smartmatch and the
smartmatch aspects of of givwhen.
