Rakudo as of r27393 can't handle multiple declarations in a single "my"​:

my (@​a, @​b); say @​a
Scope not found for PAST​::Var '@​a'
my @​a, @​b; say @​a
Scope not found for PAST​::Var '@​b'

Implementing that shouldn't be too hard, and would fix quite some of the
spec test failures.

Cheers,
Moritz

We'll work on this one.

my @​a, @​b; say @​a
Scope not found for PAST​::Var '@​b'

Rakudo has this one correct -- according to S03, scoping
multiple variables with 'my' requires the parens​:

: my $a; # okay
: my ($b, $c); # okay
: my ($b = 1, $c = 2); # okay - "my" intializers assign at runtime
: my $b, $c; # wrong​: "Use of undeclared variable​: $c"

But is that really the error message you want to be giving for that syntax
error? The double spaces suggest that something internal isn't even
interpolating as expected, due to a the string form of a name being missing.

You're correct, the error message itself needs updating. At the moment
the error is being caught during code generation (in PCT), whereas
ideally we'd like to catch it during the parse (in the action
method). At that point we can give a better error message.

As of 29505, 'my (@​var1, @​var2);' works, and 'my @​var1, @​var2;' gives
the proper "Scope not found for PAST​::Var '@​var2'" error message, so I'm
resolving this ticket.
