struct var0;struct r{}def a{("{(var0(v:=array variant<v:int>())<|@(r)=>@:var0=>0[(0)[0]as r])>0}");}

tuple var0{}[export]def r{@capture(=v){}
@capture(=v){}
@capture(=r){}
@capture(=r){}
@capture(=r){}
@capture(=r){}
@capture(=r){}
}tuple v{}struct var3{r:l<l<b<v>>>
r0<-[for(v in"");array tuple<variant<v:var0 const,v:var3>,variant<r:int>,array<bitfield>>()]
}[export]def n{}

Below is the type loops again:

class var0;[export]def r{}enum var0{}[export]def var0(v,r=@{var{}}finally{var0()
[for((v)in 0);([])!=0]>([])
}[0]){}finally{}def a{("{(var0())}");}

def v0r0(r,v<-([[v0r0()]-::r()$(){}]);r0=0){}enum r{}def n{("{v0r0()}");}
