Things that NQP needs

This list is based on discussions with pmichaud and unimplemented items in the grammar, src/Grammar.pg.

Last updated: 2007-11-24

Code

• & sigil

  Handle the mapping between &foo and 'foo' subroutines.

• return statement

  While it seems like implementing return would be a simple matter of generating PIR .return statements, it's not quite that simple, because return statements can occur inside of nested blocks.

  So, we need an NQP return statement to throw a "return exception", which is then caught by the outermost block of the currently executing subroutine and then used as the argument to .return.

  Fortunately, the new design of S05 means that we don't really need return statements for developing action grammars, so this is no longer as much of a priority as it was.

Tests

• More tests for method ops

  We should be able to load an external module (Pm suggests Test.pbc) and exercise methods using that.

• Match variable access $/

• More tests for scalar context $( ... )

• More tests for list context @( ... )

• Variables with twigils

• More tests for optional arguments and parameters

• More tests for named arguments and parameters
