for people to work on some of the later milestones even if the
earlier ones aren't complete.
-In addition to the above list of major features, the following list contains
-various smaller tasks that we should accomplish to get the number of tests in
-spectest_regression that we are currently skipping down somewhat. Some of
-them are probably good if you are looking for a more gentle entry point to
-Rakudo development than some of the bigger items listed above.
+Here's a more detailed list of current to-do items:
+
+* Implement Whatever (*) in array indexes
+ - need an implementation of Whatever
-* Implement whatever (*) in array indexing: @foo[*-1]
* Implement Rat data type
+ - awaiting clearer spec/understanding of the relationship between Num and Rat
+
* Implement infinite ranges
-* Implement return type coercion ("as") and constraint ("of")
-* Fix issues with Int type constraint when we get an Integer PMC back, and
- similar
+ - awaiting Whatever implementation
+
* Implement prefix:<\> operator
+ - Need some clarity in spec and spectests for Capture objects
+
+* Implement return type coercion ("as") and constraint ("of")
+
+* Fix issues with Int type constraint and Integer PMCs
+ - awaiting .HLL capabilities
+
* Finish implementing radix notation (see S02-literals/radix.t for details)
+ - C code in Perl6Str.pmc needs refactoring and updating
+
* Implement eqv and === operators
+ - No dependencies
+
* Implement .perl on code objects
-* Investigate various issues with .perl on recursive data structures (see
- S02-names_and_variables/perl.t)
-* Make junctions in boolean context return a junction of True/False
+ - Need a clarification of what .perl should return here
+
+* Comparison operators on junctions should return junction of True/False
+ - Needs junction dispatcher
+
* Investigate junction of code object failures (S03-junctions/misc.t)
+ - Likely depends on junction dispatcher
+
* Implement missing infix:<xx=> operator
+ - Awaiting parser improvements to properly parse and
+ handle infix_postfix_meta_operator
+
* Fix modulo bugs and MMD-related bugs for += and -= (S03-operators\arith.t)
+ - Awaiting parser improvements to properly parse and
+ handle infix_postfix_meta_operator
+
* Implement NaN and Inf
+ - Need to determine if Parrot will support NaN/Inf directly, or if
+ Rakudo should write these
+
* Empty contextualizer @() should be same as @($/)
+ - File an RT ticket for this with test case
+
* Fix MMD-related bugs in S03-operators\range.t
-* Implement inifx:<orelse>
+ - Need to refactor comparison ops in rakudo to avoid or handle 'cmp'
+
+* Implement infix:<orelse>
+ - Requires some specialized structures, perhaps a new PAST::Op pasttype (PCT)
+
* Fix bugs with nested ?? !!
+ - Awaiting parser improvements (PGE)
+
* Implement state variables
+ - Need to fix lexical and initialization issues (Parrot)
+
* Implement last/redo/next/continue control exceptions
+ - Needs last/redo/next/continue exceptions in PCT (PCT)
+
* Fix .{"key"} parsefail when (hash index into $_)
+ - likely parser bug (Rakudo grammar.pg)
+
* Finish implementing given and check/fix tests in S04-statements\given.t
+ - Need resumable exceptions (Parrot)
+
* Implement CATCH blocks
+ - Need some parser improvements, updates to 'try' handling
+
* Implement loops and conditionals taking pointy blocks
+ - Needs some minor PCT updates (PCT)
+
* Make m/.../ syntax for constructing a regex work
+ - Update grammar.pg (short-term), or wait for STD.pm integration
+
* Fix problem with using Str as a type constraint or in MMD
+ - File an RT ticket for this?
+
* Fix lambda expression parse bug when used as rvalue
+ - Needs parser/PGE fix (PGE)
+
* Implement ::?CLASS
+ - Update in actions.pm to define compiler variable
+
* Implement/fix adverbial blocks
+ - Needs update to grammar, may need to wait for LTM in PGE
