^^ Common things that are known to have problems or not work in Rakudo
(As of 2009-01-02.)
Where appropriate, provide a reference to the corresponding RT ticket. Note that we aren't trying to make a list of all known bugs -- that's what RT is for. This should just be for the common issues that people will want to be aware of or work around when playing with Rakudo.
* arrays in list declarations -- e.g., my ($b, @a) = ...
* arrays and hashes as parameters in methods/subs
* reading array/hash elements causes them to autovivify ("RT #61882"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61882>)
* incorrect parsing of blocks followed by 'if', 'unless', 'while', 'until', 'given', etc. ("RT #57876"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=57876>)
* accessing outer lexicals from eval
* lazy lists
* lazy ranges
* prefix and postfix hyperoperators
* //= ("RT #61880"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61880>)
* operator overloading, defining new operators
* nested package/grammar/class declarations
* autothreading of methods over Junctions
* slices/indexing of Ranges ("RT #61848"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61848>)
* filling positional parameters by named argument ("RT #54808"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=54808>)
* assigning values to %*ENV ("RT #57400"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=57400>)
* methods on Match cannot be used as rule names ("RT #57864"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=57864>)
* some things that should be readonly aren't
* autovivification of undefs to arrays/hashes
* my $x; ++$x; ("RT #61924"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61924>)
* my Int @a; ("RT #61926"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61926>)
* Perl 6 closures in regexes (although it is possible to execute some PIR)
* code assertions in regexes -- i.e., <?{...}> and <!{...}> (but PIR forms are available)
^^ Things that do (mostly?) work in Rakudo
See also the twitter feed at <http://twitter.com/rakudoperl>.
* scalar, array, hash variables
* classes, methods, roles
* for, loop, repeat, while
* if, elsif, else, unless
* junctions
* selected infix hyperoperators, reduction operators, cross (X) and zip (Z) operators
* slicing syntax
* chained comparison operators ( if 1 < $a < 100 { ... } )
* whatever star in slices
* closures
* currying (i.e., .assuming)
* simple next/last/redo
* given/when
* take/gather
* pointy blocks ( -> $foo { ... } )
* open (:w or :r) and slurpy files (and that is all, IO not implemented yet)
* eval some code
