<masak> rakudo: sub f(@a, $i=0) { $i ~ "[{map { f($_, $i + 1) }, @a}]" }; say 
f([[], [[]], []])
<p6eval> rakudo 7347ec: 0[1[] 2[3[]] 4[]]␤
* masak adds that to #70469
<pmichaud> masak: I suspect that's related to dispatch/binder changes, but 
that's just a 
guess.
<masak> pmichaud: same here.
<jnthn> Me too now I see it as a sub example.
<jnthn> masak: Default param to blame?
<masak> jnthn: I'll check.
<masak> rakudo: sub f(@a, $i) { $i ~ "[{map { f($_, $i + 1) }, @a}]" }; say 
f([[], [[]], []], 0)
<p6eval> rakudo 7347ec: 0[1[] 2[3[]] 4[]]␤
<masak> jnthn: no.
<jnthn> masak: Aww.
<moritz_> masak: dammit. I was just about to put it into 
S06-signature/defaults.t
<jnthn> lol
<masak> :)
<pmichaud> looks to me as though a new lexpad isn't being created somehow.
<jnthn> Yeah, the problem is in there somehow.
<moritz_> masak: and now I realize it's the wrong place, and I have no clue 
where to put it
<masak> moritz_: sorry :D
