@extern
def output_int(x: int32):
    ...

def run() -> int32:
    a = (1, True)
    output_int(int32(a[1]))
    return 0

results in:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "Cannot unify variable 8 with bool due to incompatible value range at line 7 column 16"', nac3standalone/src/main.rs:65:35

Two problems here:

~~int32(bool) is valid and should be supported.~~ #60
the reference to "variable 8" in the error does not mean anything to the user.

```python @extern def output_int(x: int32): ... def run() -> int32: a = (1, True) output_int(int32(a[1])) return 0 ``` results in: ``` thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "Cannot unify variable 8 with bool due to incompatible value range at line 7 column 16"', nac3standalone/src/main.rs:65:35 ``` Two problems here: 1. <s>int32(bool) is valid and should be supported.</s> https://git.m-labs.hk/M-Labs/nac3/issues/60 2. the reference to "variable 8" in the error does not mean anything to the user.

Can we split this into two issues? The 1st one is simple but the second one is very complicated.

sb10q changed title from ~~poor error message, int32(bool) should be supported~~ to poor error message involving tuples and type conversion error
