Iterating through a list of lists seems like it loses type information

Disclaimer: I don't know if this is supported or expected to work.

Using v0.4-DEV on x86-64 Linux, if I try to access an array using an index from a list of list of indices (List[List[int]]) while iterating, Cyber panics (third print in the code). It seems like maybe the type information is wrong because if I wrap the value in int(...), then everything works fine (second print in the code). Accessing outside of a "for each" loop seems to work fine as well (first print in the code).

Minimal code sample:

var nestedIndices = List[List[int]]{ List[int]{1} }
var values = List[int]{3, 4, 5}

-- Works
print values[nestedIndices[0][0]]

for nestedIndices -> indices:
  -- Works
  print values[int(indices[0])]
  -- panic: Out of bounds
  print values[indices[0]]

I'm expecting the program to print the number 4 three times. Instead, I see:

4
4
panic: Out of bounds.
