It thinks it's interpolating a variable $x::... and then it gets stuck
because it sees $y instead of the rest of a variable name. You can use
braces to control what's part of the name:
pyanfar Z$ 6 'my $x = "abc"; my $y = "def"; say "{$x}::{$y}"'
abc::def
Otherwise, you couldn't interpolate the name of a variable $x::y in some
other module.
