Error with built-in type function when running a script via larky-runner

When using the larky-runner executable to interpret a larky script, attempting to use the built-in type() function results in the following error:

net.starlark.java.eval.StarlarkEvalWrapper$Exc$RuntimeEvalException: EvalException thrown during Starlark evaluation ('type' object is not callable)
Caused by: Traceback (most recent call last):

Note that type() works when using the interactive larky-runner prompt

Advised solution

N/A (unknown)

Testing scenarios

1. Create a test file named test.star with the following content:

type(1)

2. Execute the script:

larky-runner -s test.star

Expected result

A successful run with an exit code of 0

Observed result

The above error message with an exit code of 1
