<jnthn> I think the parser is gonna need to commit after seeing repeat, fwiw
* masak submits stdbug
When I feed this program to STD:
do { } for 1;
I get the response
Unsupported use of do...for; in Perl 6 please use repeat...for at
But feeding
repeat { } for 1;
into STD gives
Undeclared routine: 'repeat'
So one way or another, std is inconsistent.
By current spec,
+Order::Decrease == 1
+Order::Same == 0
+Order::Increase == -1
Not only does this numification run counter to popular interpretations of "Increase" and "Decrease", but also requires a different interpretation:
say 5 cmp 7
OUTPUT: Increase
(From the LHS, you must increase to get to the RHS)
say +(5 cmp 7)
OUTPUT: -1
(From the RHS, you must go down (subtract/add negative) to get to the LHS)
I don't know about you, but this weird numification of words in addition to the differing interpretation between the object and its numification is broken. I recommend Decrease == -1 and Increase == 1.
std thinks that 3 !=3 is about assigning the negated three instead of a comparision.

On a fresh Ubuntu 14.04.1 box with perl 5.18.2, STD's make snap
errors out:
Compiled lib/Stash.pm6
Compiled ./CursorBase.pm6
Compiled ./Cursor.pm6
===SORRY!===
Preceding context expects a term, but found infix = instead at STD.pm6 line 2787:

make: *** [STD.pmc] Error 2
The build also produces lots of warnings about given
/when
being deprecated (but they don't stop the build from happening).
In the following example rather common $|++
idiom makes "Bogus statement" error. I think it should report "Unsupported use of" error instead.
glitchmr@strawberry ~/g/std> echo '$|' | ./viv -

Unsupported use of $| variable; in Perl 6 please use :autoflush on open at (eval) line 1:
