Difficulty running bindc_03.py in regular CPython

I thought I had the PYTHONPATH figured out, but `CType` can't be found. ``` PYTHONPATH=/Users/brian/Dropbox/Mac/Documents/GitHub/lpython/integration_tests/../src/runtime/lpython:/Users/brian/Dropbox/Mac/Documents/GitHub/lpython/integration_tests/.. python bindc_03.py Traceback (most recent call last): File "/Users/brian/Dropbox/Mac/Documents/GitHub/lpython/integration_tests/bindc_03.py", line 12, in def g(a: CPtr,...

Improve dictionaries, sets, tuples, lists for all backends

1

We have initial implementation working, we now have to extend it to work for all backends well, support printing, etc.

Print all error messages ?

1

I'd like a mode or command-line switch that tells LPython to print all error messages it can find in a file as opposed to the current behavior, which seems to...

Ensure more types and cases are handled, that it works with all backends (C and LLVM), that it works in "JIT" mode using the lpython decorator from CPython.
