I think the problem is IO::Socket.read() returns a Blob not a Buf. ~ has a Buf, Buf variant : https://docs.raku.org/language/operators#infix_~
But not a Blob one. Buf does Blob but not vice versa. I think you need to transform the output from .read into a Buf if you want to use the ~= how you want to. Would this work? my Blob $read = Buf.new; $read ~= Buf.new( $socket.read(1024) ); On Tue, 11 Feb 2020 at 10:46, Kevin Pye <kevin....@gmail.com> wrote: > > ~ works fine for concatenating Bufs; For example: > > my $a = Buf.new(1,2,3); > my $b = $a ~ Buf.new(4,5,6) > > will assign correctly to $b. > > I can't work out what the problem is here, despite trying various > combinations.
