Potential index out of bounds error when accessing
new_generic_types[idx]. The variableidxrepresents the position in theargsarray, butnew_generic_typesonly contains entries for generic and optional arguments without explicit types.For example, with
fun foo(a: Num, b),argshas 2 elements butnew_generic_typeshas only 1. When processing argument at index 0 (a: Num), the code would try to accessnew_generic_types[0]in theTypedbranch (line 236), which doesn't make sense since typed arguments don't add tonew_generic_types. When processing argument at index 1 (b), it would trynew_generic_types[1]which is out of bounds.The old code used
new_generic_types.remove(0)which correctly dequeued generics in order. Consider maintaining a separate counter for generic indices or reverting to the dequeue approach.
