You got the order of operations wrong.
Method calls happen before prefix operators
These are identical
+@a.so
+(@a.so)
@a.so.Numeric
@a.Bool.Numeric
+?@a
As are these
+«@a».so
+«(@a».so)
@a».so».Numeric
@a».Bool».Numeric
+«?«@a
Postfix operators also ha
Hi Richard,
I don't think it's a bug. In:
put +@a.so;
the @a array is coerced into a Boolean value (True) by the so method, and
the resulting Boolean value is then coerced into an integer by the +
operator.
Cheers, Laurent.

A snippet:
my @a = 1..10;
put +@a.so; # output 1
put so(+@a); # output True
put (+@a).so; # output True
This caught me because I used +@s.so when I tried to do something like:
# in a class with 'has Bool $.pass;'
return unless ( $!pass = +@a.so );
# fails with a Type
