<masak> r​: macro f($x) { quasi { "{{{{$x}}}} (just testing macros)" }

<masak> this one is indeed interesting.
<masak> TimToady​: would you expect {{{}}} or { {{{}}} } inside a qq

<jnthn> masak​: I think the answer is that quasis only have meaning in
the MAIN language, so you need to be inside the closure.
<masak> I think that's sane, yes.
<jnthn> er, please confirm STD actually belives what I just told you :P
