There are some common misuse patterns in TorchScript that we should issue clear error messages for instead of generating generic error that doesn't capture root cause of error.

Here are a few examples:

• Attempting to construct a nn.Module inside TorchScript. This currently errors out because TorchScript would attempt to compile __init__() method of module, which usually contains a call

Implements {DataFrame,Series}.empty

Tests for following standard libraries seem to be missing. Although some libraries might be difficult to test (such as random.egi or io.egi), it'd be nice to have some tests that make sure all the functions in these libraries can be (at least) executed without dynamic errors.

• lib/core/io.egi
• lib/core/random.egi
• lib/core/shell.egi
• lib/core/sort.egi
• Every
