Code:
say Buf.new('0')

Result:
Type check failed in initializing element #0 to Buf; expected uint8 but got Str 
("0")
  in any  at gen/moar/Metamodel.nqp line 1727
  in block  at /tmp/9PmeQTevmg line 1

Actually thrown at:
  in any  at gen/moar/Metamodel.nqp line 3072
  in any  at gen/moar/Metamodel.nqp line 1727
in block  at /tmp/9PmeQTevmg line 1



It points three times to a line in Metamodel.nqp, and only once to the actual 
user file. Perhaps there is a way to improve it? Maybe not just for this case, 
but for any exception?
