^^ Common things that are known to have problems or not work in Rakudo
(As of 2009-01-10.)
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.
* 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
* handles handle only String and List of String, Tepy and Regex not work yet
* 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 Int @a; ("RT #61926"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61926>)
* variables in regexes ("RT #61960"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=61960>)
* .want on Routines, Blocks or Closure not implemented yet (but .arity works)
* Perl 6 closures in regexes (although it is possible to execute some PIR, on the form {{{{ PIR HERE }}}})
* code assertions in regexes -- i.e., <?{...}> and <!{...}> (but PIR forms are available, as <? {{{{ PIR HERE }}}}>)
* interpolations of arrays, hashes, and method calls in strings ("RT #62198"<http://rt.perl.org/rt3/Public/Bug/Display.html?id=62198>)
** Note that the { ... } form is a usable workaround
^^ Things that do (mostly?) work in Rakudo
See also the twitter feed at <http://twitter.com/rakudoperl>.
* $scalar, @array, %hash variables, my and our declaration
* sub, multi sub, sub and methods signatures with types and defaults
* OO stuff mostly works: classes, methods, submethod, roles; has, self, is, of, does, handles etc.
* for, loop, repeat, while
* if, elsif, else, unless, given, when
* junctions (auto-threading partiality works )
* 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
* take/gather
* pointy blocks ( -> $foo { ... } )
* open (:w or :r) and slurpy files (and that is all, IO stuff mostly not implemented yet)
* eval and try/CATCH
* Ranges
* max, min built-ins (but minmax not implemented yet)
* m// .trans and .subst (s// not implemented yet)
* grammar and .parse method to match it
* .pick, rand
* set context: list and .list, item and .item, ~, hash and .hash
* .arity (but .want not implemented yet)
