Fuzzer bugs

Assertion failure:

require UnitTest
struct template var0;[export]def v(r:var0){}[export]def y{}

Folding:

class v{}struct template v2{r=i((3?reinterpret<bitfield<>>(([],)<(0>t))as r*([{for((v)in@@o[[]]>(2)>5,(v));(0[((3>(k())>new<a<v>>()-0)) as  t8 ])%(9)%(99)% o }
].) ?[ (T )] .. 2:[  ]), (3));
}enum v{
}

[export]
def ma{
 return  float4 ( uint (),2,-9,3);
}

type inference:

def var0(v;r:var0<-{}){}tuple var0{}[export]def n{while(var0<|0){}finally{([])}}
