: Oh, and under the S02 rules above (the index expression inherits
: outer context on RHS), Pugs currently does this:
:
: $_ = %x{ 1, 2 }
: --- reduces to ---
: $_ = %x{ [1, 2] }
: --- reduces to ---
: $_ = %x{ "1 2" }

: Which is, well, very surprising. Where did I get wrong?
I think S02 is probably wrong. It should be unknown/list context.
Sorry for the short answers, but I'm in Russia behind a flakey network
connection, which is probably going away entirely at any moment (the
network connection, not Russia.) I can clarify more next week when
I get back.
