in thread printing hashes

Perl 6 will interpolate spacetab-separated pairs, one per line, though the restrictions on interpolating arrays and hashes are tightened a bit to avoid accidental interpolation of email addresses and printf formats. You have to do something like: 
    say "Array is @array[]";
    say "Array is {@array}";
    say "Hash is %hash{}";
    say "Hash is {%hash}";

Only scalars interpolate without some kind of bracketing.

The space-separated form was chosen to make it easy to split on whitespace, but it's expected that most hash interpolations will in fact specify some more explicit format: 

    say "Hash is %hash.as('%s => %s', ', ')";

    Looks like pugs does most of this: 

    $ pugs -e'my @array=1..5;say "Array is @array[]";'
Array is 1 2 3 4 5
$ pugs -e'my @array=1..5;say "Array is {@array}";'
Array is 1 2 3 4 5
$ pugs -e'my %hash;%hash{"a".."c"}=1..3;say "Hash is %hash{}"'
Hash is a    1
b    2
c    3

$ pugs -e'my %hash;%hash{"a".."c"}=1..3;say "Hash is {%hash}"'
Hash is a    1
b    2
c    3

$ pugs -e'my %hash;%hash{"a".."c"}=1..3;say "Hash is %hash.as(q(%s => 
+%s), q(, ))";'
