Looks like I got that irrefutability bug too.

Rather than withFilter, for a subset of for comprehension structures.
Not sure if this was somewhat by design - only seems possible because
refchecks was only looking for nme.filter, not nme.withFilter, so
perhaps this was intended as some secret irrefutability backchannel?
Really have to document that sort of thing if it's intentional. I
assumed it wasn't and unified everything.

The parser has always been confused about tuple patterns in
for comprehensions. It thinks it can fail to recognize an
irrefutable pattern and have it removed in refchecks, but it
is sadly mistaken, because the unnecessary filter has a tendency
to fail the compile in typer.
Look more intently for irrefutable patterns and don't insert
the unnecessary filter. Closes SI-5589, SI-1336.

extrapolate GADT skolems: only complicate types when needed
make sure we only deskolemize GADT skolems after typedCase

Having now experienced the unbelievable difference it makes to
have one's voluminous debugging output effectively color-coded,
I had to librarize the ansi codes in order to use them. This
could all go in the standard library, or as soon as I can easily
make use of compiler dependencies, a separate library altogether.
For now it hides away in scala.tools.util.color.

* +: does head/tail decomposition on any Seq
* :+ does init/last decomposition on any Seq
* Both preserve specific Seq types.

It's more of a "dump what it says to a file so we'll know if
any of this ever changes" than a "test" per se. It could use
some wheat/chaff/nonsense/sense sorting. Still, it would
be great to have more stuff like this.

This reverts commit f987afe55e6d4f71c7e9ad10d1ca9f6120dc1132.
Looks like somebody misread the grammar. Look for it to
return in one of paulp's exclusive branches for today's
discriminating hacker.

At least, I think so.
|
| | |
| | |
| | |
| | |
| | | |
Type application and operator notation could not formerly be
mixed. Now they can, as the grammar has always suggested.

(Looks like there is more range position breakage yet, but
this gets the outermost layer.)
Channeling my struggles into a slightly easier future.

Have you often thought that programming is just like the
movie 'Hackers', only with less rollerblading? Now that we
have @inline skates, that last caveat can be retired.
It's just like the movie 'Hackers'.

...since it works from source. The parser must be forcibly restrained
from adding a bogus constructor, but other than that it's pretty much
smooth sailing. To give an idea how smooth, if I change scala.Short like so:
trait Bippy extends Any
final class Short extends AnyVal with Bippy
Then it just works, at least until the fiction is revealed.
scala> def f(x: Bippy) = x
f: (x: Bippy)Bippy
scala> f(5)
<console>:9: error: type mismatch;
found : Int(5)
required: Bippy
f(5)
^
scala> f(5: Short)
java.lang.ClassCastException: java.lang.Short cannot be cast to scala.Bippy
at .<init>(<console>:9)
at .<clinit>(<console>)

And grueling recovery from branch drift.
Merges a portion (and only a portion) of topic/inline into master.
The major changes which come with this merge are:
AnyVal is unsealed, can be extended directly.
ScalaObject is no longer with us.
