Pm Wants

• @*ARGS

Coke Wants

• Ability to override vtables from NQP.

Plumage Wants

Bold Highlights indicate top priority features (usually blocking Plumage’s progress in some area).

• Q:PIR and pir::
  • Support inout params of PIR opcodes in the pir::op__params() syntax (I think NQP already supports this — give an example of the specific opcode in mind. —Pm)
• Signatures and calling
  • Named argument flattening (now added by sorear++ —Pm)
• Containers
  • Full hash constructor syntax
• Signatures and Calling
  • Calling computed sub/method name
    • self/$obj.$method()
    • Foo::Bar::($sub_name)()
    • Something equivalent to the second item, but in the current package. "$sub_name"() and ($sub_name)() are likely invalid.
• Grammars/Rules/Regexen
  • Get next match on same string
• Callables
  • Cloned closures (now added —Pm)
• Classes
  • CREATE (or other simplification of overridden new() methods)
• General syntax
  • Statement modifier style for
• PIR output
  • Use fetch and vivify opcodes

Kurahaupo suggests

• that “get next match” should perhaps be done by creating an iterator on a lazy /g match.

sorear’s wishlist

• Quasiquotey syntax for abstract syntax trees (PAST only is an acceptable approximation)
• Mixins (they’re like roles, but with no fancy logic; basically just a class inside a sub)
• Native types (will make writing optimizers easier… bacek wants these for lorito’s ops-nqp)
• Loop control (done)
• Flatten arrays (done)
• Signature unpacking of multiple return values
• Returning multiple values
• Tailcalls
• Subroutine traits (just pirflags, really)
• @*ARGS
• General anonymous hash constructors
• An optimizer :)
• Better error messages. “Unable to parse blockoid” fifteen lines away… I want to do better.

Completed Features

• Signatures and calling
  • Optional, named, named optional params (already done —Pm)
  • Param defaults (already done —Pm)
  • Slurpy params (already done —Pm)
  • Positional argument flattening (Added in 8c211fe)
  • Fat arrow (=>) named argument syntax (added in 7c9ba0a)
  • Calling computed sub/method name
    • self/$obj."$method_name"() (added in r42789)
• Callables
  • Pointy blocks (added in 992b220 —Pm)
• Containers
  • Iterate over hash kv pairs (requires either real pairs or pointy blocks with params) (pointy blocks with signatures done, see above)
  • Empty array and empty hash constructors (now done in 2471f02)
  • Full array constructor syntax ([] array constructor available in 2471f02)
• Strings
  • Closure interpolation (added in 5559916 —Pm)
• Floats
  • Support for them (added in 19c949e)
• Classes
  • Attribute declaration (already done —Pm)
• General syntax
  • Statement modifier style if/unless (added in b7ce35e)
  • Statement modifier style while/until (added in 8d6dfe2)
  • try and/or CATCH (added in ef7eef0)
• Variables
  • “Globals” declared and initialized by a module without aid of mainline; could be any of:
    • GLOBAL pseudo-namespace + cross-namespace variable references (@GLOBAL::ARGS) (added in r42541)
    • Contextuals (@*ARGS) look in PIR’s ‘namespace []’ as fallback (added in r42541)
    • Compile-time lexical export (declined)
• split(/regex/) in nqp-setting
