You're using doubles quotes for the string you're passing to Raku.
This means the Shell will do variable interpolation. So it see's "my
$map = Map.new()" and puts the value of it's variable $map in their.
But it doesn't exist. So Raku gets "my = Map.new()" (Note the space
where $map was). And complains. (You can see that in the error).
I'd advise *always* suing single quotes to pass strings into Raku on the
command line. If you need single quotes in your code use q[] instead.
So :
p6 'my $map = Map.new("a", 1, "b", 2); say $map{"a"}; say $map{ "a", "b"
};'
Should work just fine.
%e := Map.new binds %e to the Map if you did %e = Map.new it will treat
the Map as the first element in a list and probably complain.
On the other hand $e = Map.new is assigning to a Scalar so it doesn't
expect to be taking a list of values.
If that makes sense?

Hi All,
I am going through the examples on
https://docs.perl6.org/type/Map.html
$ p6 "my $map = Map.new('a', 1, 'b', 2); say $map{'a'}; say $map{ 'a',
'b' };"
===SORRY!=== Error while compiling -e
Malformed my
at -e:1
------> my⏏ = Map.new('a', 1, 'b', 2); say {'a'};
What the heck is a 'Malformed my"? I copied and pasted
from the second set of examples.
And why is the first example:
%e := Map.new
and the second example
$e = Map.new
?
Many thanks,
