Announce: Niecza Perl 6 v18
This is the eighteenth release of Niecza Perl 6, as usual scheduled on
the last Monday of the month.
You can obtain a build of Niecza from [1]. This build contains a
working compiler as a set of .exe and .dll files suitable for use with
Mono or Microsoft .NET. If you wish to follow latest developments,
you can obtain the source from [2]; however, you still need a
binary for bootstrapping.
Niecza is a Perl 6 compiler project studying questions about the
efficient implementability of Perl 6 features. It currently targets
the Common Language Runtime; both Mono and Microsoft .NET are known to
work. On Windows, Cygwin is required for source builds only; see the
README for details.
List of changes
[Breaking changes]
substr now returns a read-only value in accordance with specification changes.
To modify the substr return value, use substr-rw (new in this release).
Default new() methods, when passed arguments to initialize @.attributes,
now treat the argument as a whole array. In other words,
(class :: { has @.foo }).new(foo => [1, 2, 3]) no longer results in an
additional level of boxing.
[Exciting major features]
Exceptions and warnings generated within a span of call-less statements
are now much more likely to give the correct line number. (Exciting to me!)
Many setting operators like + are now multis and can be extended by user code.
[Minor changes]
Added ms// syntax (Solomon Foster).
Added Rat.Rat, Rat.norm (Solomon Foster).
Numerous bug fixes.
Niecza::Benchmark has been rewritten and is now a bit more robust.
[Major internals changes]
Containerization of values is no longer mandatory; bare values are now used
everywhere read-only Scalars were in v17. In particular, the NewROScalar
function has been removed.
